Peter Gregson on taking Bach to the dancefloor

Cellist Peter Gregson's show at the Bristol Proms is a particularly different concert experience - a dance collaboration that encourages the audience to get involved with the music itself, while Gregson plays Bach to accompany.

As he explained to Jane Jones before the afternoon workshop kicked off, it's a surprisingly tricky experience to accompany a group of dancers as they learn some new dance moves for Bach cello suites.

"It totally changes what you do and how you do it, so it's been quite a long road of re-learning!"
