It's surely one of London's more unusual performances: this week, you can hop onto the No 9 bus and be greeted by singers experimenting with sound and motion, as part of artist William Mackrell's artwork Gaps, glitches and speed bumps.
Between 10 and 13 September (from 11.30am to 4.15pm) professional singers, spanning blues, classical, operatic and electronic improv will absorb the swerves and bumps of bus travel in a unique performance. They'll be accompanied by artist Mackrell's own response to the movement: he'll be creating a line drawing mapping the movement of the journey on a circular musical score.
There are four performance buses travelling each day. If you want to see the 'show', simply show up at one of the stops with a loaded Oyster card, or with your contactless payment card ready. Follow @Liveonthebus on Twitter for up-to-the-minute information.
We'd love to tell you more, but that's really all the info we have. Catch the No 9; see bonkers art being made. Enjoy.
Gaps, glitches and speed bumps runs 10-13 September, 11.30am to 4.15pm on the Route No 9, between Aldwych and Hammersmith. Visit sculptureshock.rbs.org.uk to find out more.
