Rock Choir performance

Rock Choir are taking over the first floor balcony of Derby Market Hall on Sunday 31 January, for a performance that's more of a singing flash mob than a formal concert. It's a short one, running from 12:25pm to 12:55pm, so it's the kind of thing you can drop into while you're already out and about in the city.

Rather than a single choir on a stage, this brings together more than 50 members from several local Rock Choir groups, all teaming up with Treetops Hospice. They'll be working through a set of familiar tunes, the kind of songs you'll recognise and can't help but hum along to. The whole thing is billed as a high-energy affair, and the idea is that you'll be tapping along rather than sitting in silence.

Rock Choir describes itself as the UK's award-winning contemporary choir experience, and that's where the flash mob side of things comes from. Instead of a traditional concert, it's a larger group of local singers coming together in one place, and with over 50 of them on the balcony, it should be a fair bit of sound filling the hall. The partnership with Treetops Hospice adds another layer to it, too.

It's free to watch, so you don't need to book or pay anything to stand in and listen. Just head up to the first floor balcony of Derby Market Hall on Sunday 31 January, between 12:25pm and 12:55pm.
