Terry Riley at 80: IN C plus 3

One Church, Gloucester Place, Brighton, Saturday, June 27, 8pm, £11, 01273 606312

LOST Property formed last year to produce Fort Process, a sound art festival in Newhaven Fort.

For their second event they are celebrating minimalist composer Terry Riley’s 80th birthday with a concert based around his most famous work.

“IN C has been recorded hundreds of times and performed all over the world in the last 50 years,” says Lost Property’s Alistair Strachan.

“The idea of it entered his head during a 20-minute bus ride after his regular piano jazz session at Gold Street Saloon in San Francisco. It was written out in full over the space of an evening.

“We're all involved in improvised and experimental music, and so for us it's a bit like tracing back the family tree: you see that Riley was inspired by tape loops over half a century ago, and then you hear current artists playing with tape and you make connections that you didn't know were there before."

The instrumentation for this performance uses wind, strings, tuned percussion and piano, with vocal contributions from folk singers Mary Hampton and Jo Burke.

Percussionist Adam Bushell has the task of maintaining the constant pulse that characterises the piece.

"Essentially he will be hitting middle C on the vibraphone at 110bpm for an hour,” says Strachan. “Look out for the 1,000 mile stare on his face as the piece concludes."

Supporting the piece will be selections from and inspired by Riley’s back catalogue.

Experimental musician and purveyor of vocal cut-up techniques Duncan Harrison will create a piece based on Riley’s tape collage You’re No Good. Andrew Greaves’s composition Octabeast is inspired by Riley’s long-form compositions such as Persian Surgery Dervishes. Daniel W J Mackenzie will play One Church’s organ, and pianist Asami Nishimura will play a lesser-known Riley piece Keyboard Study #1.
