As the 2025 BBC Proms season gets underway, Martin Cullingford is joined by Tim Parry and Hattie Butterworth select their top picks. From Rachmaninov with Yunchan Lim and the UK premiere of Anna Thorvaldsdottir’s Cello Concerto to a late-night tribute to Arvo Pärt and a rare performance of Delius’s A Mass of Life, the team reflects on the Proms’s cultural significance, its breadth of programming, and the enduring tradition of live music at the Royal Albert Hall.
