In 1999 the musician Warren Ellis clambered onstage at the Royal Festival Hall to retrieve a piece of chewing gum. The gum was deposited there by Nina Simone, who had chewed it throughout her concert that night. Fast forward twenty-two years and Ellis has written a book inspired by the piece of gum, now enshrined in its own glass case, on a specially built gum plinth. Kate Molleson caught up with him to find out more about a story which goes to the heart of artistic belief, generosity and affirmation. It was a book he never really set out to write, but then couldn’t not write.

Following on from Music Matters’ meeting with Steve Reich two weeks ago, Kate delves further into the origins, development and lasting legacy of minimalism. She talks to composers Linda Catlin Smith, Nate Wooley and Julia Wolfe to find out how a disparate group with new ideas continues to inspire, and also hears from pioneers such as Philip Glass and Pauline Oliveros about the mentality of anti-hierarchy and participation which changed the musical landscape.

Laurence Crane is one of the most beloved figures in British contemporary music, his work is full of surprise, fondness, wit and wisdom. As a successor to a certain sort of minimalism, he lets us hear humble wonders in the everyday. Celebrating his sixtieth birthday this year, he met up with Kate at one of his favourite performance spaces to look over his constantly surprising career and oeuvre.

And as orchestras and musical institutions look at ways to represent diversity among their ranks, Kate talks to John Shortell of the Musicians’ Union, and Diversity and Inclusion consultant Chico Chakravorty, about what are the most effective ways to achieve this.
