Classical gig of the week: Steve Reich's Radio Rewrite, various venues

Rare appearance: American minimalist master Steve Reich

What is the sound of four hands clapping? One possible answer is Clapping Music, American minimalist master Steve Reich's seminal showpiece of two-person body-percussion.

And this week, in a rare series of appearances, the 76-year-old composer performs this most portable icon of 1970s systems music by way of a pattern-shifting prelude to a London Sinfonietta tour that also includes the world premiere of Reich's Radio Rewrite, inspired by Radiohead, and more.
