Two world-renowned pianists from Venezuela and Georgia talk to Kim Chakanetsa about their personal and musical journeys.

Gabriela Montero grew up in Venezuela and could pick out a tune on a toy piano before she could speak. She made her concert debut aged eight and has gone on to become an award-winning and best-selling performer, who played at the inauguration of President Obama in 2009. Gabriela now lives in Spain but in recent years has begun to compose her own music, and is using her artistic voice to highlight the terrible problems facing her native Venezuela.

Georgian pianist Khatia Buniatishvili began her musical studies at the age of three. Hailed as a child prodigy she began touring internationally aged 10, and hasn't stopped since. However she says she was never pressured to have a career in music - it's simply what she loves to do. As well as gaining a reputation for a dramatic playing style, Khatia's revealing outfits have also attracted attention. She says she will continue to wear what she wants on stage, and that these comments are attempts to belittle her intellect and musical talent by focusing on her image.

Steering a small boat across oceans by yourself - why do it? Kim Chakanetsa meets two women who have been alone at sea for months - and they chat about encountering sharks, avoiding pirates and having to call their mums.

Roz Savage is the first woman to have rowed solo across three oceans - the Atlantic, Pacific and Indian. She had no background as an adventurer and in fact was a UK management consultant for years, but in her 30s she decided to do something completely different with her life. Roz says rowing the Atlantic was a huge struggle physically and mentally, but afterwards she wanted to put herself in even more challenging situations to see if she could do it, and to raise awareness about sustainability.

Australian Jessica Watson sailed around the world when she was just 16, battling storms and isolation, but also fierce criticism from those who thought she was too young. On her return after 210 days she was greeted by the Prime Minister and tens of thousands of people, and was later named Young Australian of the Year. Jessica says she did it partly to prove that young people, and young girls, can be serious and achieve incredible things, and they should not be dismissed.

Treading the boards with two musical theatre directors from Nigeria and Pakistan. Kim Chakanetsa discusses the hunt for local talent, the emotional journey of opening night and running a tight ship in rehearsals.

Nigerian theatre director and producer Bolanle Austen Peters has re-ignited Nigeria's passion for their culture through her highly successful musicals focused on local stories using local stars. She says "The talent is latent, people have it but they just need the right platform to bring it out and the individual who's going to push them". And Bolanle has done just that through her production company Terra Kulture.

Nida Butt is a theatre director, producer and choreographer from Pakistan and is responsible for revolutionising the Pakistani musical theatre scene by introducing live music and orchestras to the stage. She is the owner of Made for Stage theatre productions which has put on performances from Grease! to Nida's own original production of Karachi the Musical. Nida says "We were teaching ourselves, learning ourselves, and doing it ourselves".

Sorting out the messy business of divorce, in France and India.

Veronique Chauveau is a divorce lawyer based in Paris, where she's been practising for more than 30 years. The bulk of her work is with the rich and famous, but she also finds time for a 'reality check' through taking on international child abduction cases. And she is an undisputed expert in jam making!

Vandana Shah is a divorce lawyer in Mumbai. She learnt about divorce the hard way, when she was thrown out of the family home, and spent the next 10 years battling to get a divorce. During that time she got herself a law degree, and she is now one of the foremost lawyers at the family court in Mumbai. She regularly writes for The Huffington Post, and her memoirs are called The Ex-Files. She also started 360 Degrees Back to Life, India's first support group for people going through a divorce.

Space Scientists from the UAE and the UK discuss the missions they're involved in and what they mean to them.

Sarah Amiri is the lead scientist for the UAE's Mars Mission. Their plan is to send an unmanned spacecraft, the 'Hope', to reach Mars in 2021, where it will provide unprecedented data on the Martian climate, and also send a message to the youth of the region that there are paths available to them in science, rather than radicalism. Sarah says the people working on the Hope mission are all under 35, and 34% of them are women.

Monica Grady is a prominent British space scientist, known for her work on Beagle 2 and the international Rosetta mission, which aimed to find out where life on Earth came from. In 2014, when the robot probe Philae successfully landed on a comet, a video of Monica's hugely excited reaction went viral on the internet. She says it's no wonder she was so happy - this mission had been part of her life for 30 years.

Two women who get inside Presidents' heads, tell Kim Chakanetsa how they turn their bosses' thoughts and ideas into powerful oratory.

Sarada Peri is Special Assistant and Senior Speechwriter to President Obama. She says a good speech writer is like a ghost, and that her job is really to inhabit the President's mind on any given topic. For her, the goal isn't to emulate what he sounds like, it's to understand how he thinks. This is then represented on the page or teleprompter; with Sarada ever conscious that a single line from any one of his speeches could be lifted out of context and tweeted around the world in seconds.

When the first female President of the Republic of Kosovo came into office in 2011, it was Garentina Kraja who she turned to for her speech writing prowess, as well as her policy expertise. Together Garentina and President Jahjaga wrote a speech about the women who were raped in Kosovo during the war, and who felt they'd been ignored and forgotten since. It helped to change the whole national conversation on the subject. Garentina passionately believes in the power of words and story-telling to persuade hearts and minds.

In 2002, the French Colombian politician Ingrid Betancourt became perhaps one of the best-known hostages in the world when she was kidnapped and held for over six years, deep in the Colombian jungle, by the Farc or Revolutionary Armed Forces of Colombia.

Watching Ingrid's emotional release on TV in 2008, was a young Canadian journalist called Amanda Lindhout. A month later she herself was taken hostage at gun-point, on a work trip to Somalia. For the 460 days of Amanda's captivity, she thought about Ingrid nearly every day, inspired by the thought that she too could one day end her ordeal.

This is the first time they have spoken to each other.

Azeri journalist Khadija Ismayilova became the subject of an international release campaign last year when she was arrested and detained by her government, and her cause was taken up by human rights lawyer Amal Clooney. Khadija had been delving into the President's family businesses, and published allegations of extensive embezzlement of oil funds. She spent 18 months in prison before being given early release in May 2016, but says she is determined to continue her investigations.

Sacha Pfeiffer is an American newspaper journalist and was a member of the now world-renowned 'Spotlight' team on the Boston Globe. She and her colleagues spent years building up evidence and personal testimony of sexual abuse at the hands of Catholic priests, and the systematic cover-up of this by the Church. The resulting story caused shock-waves when it was published and the investigation was dramatised in the film Spotlight, which won the Best Film Oscar in 2016. Sacha was played by Rachel McAdams.

Get your dancing shoes on because this week Kim Chakanetsa brings together two supremely talented ballroom dancers who between them have a pile of trophies. We talk about the glamour, romance, athleticism and also the rivalries, injuries and tears that go on behind the scenes.

South African dancer Oti Mabuse has been Latin American dance champion in South Africa eight times and she is currently gracing UK screens as a professional dancer on the popular reality TV show Strictly Come Dancing. When she started ballroom dancing was a very divided activity, "We were the only black family doing Latin and ballroom, I was young, I was four and cute, but for my sisters it was extremely difficult." More recently, things have changed, she says "It's not about where you come from or what you look like, it's about what you do and what you deliver."

Alex Hixson is from the UK and has been a World Champion bronze medallist and an International Professional Rising Star Champion. Her favourite dance is the foxtrot. Alex started dancing aged 6, "before 'Strictly', so before ballroom dancing was cool. I saw a poster and told my mum that I want to do ballroom and Latin dancing and she said why? That's what old people do."
