Rainer Hersch explores the musical significance of unusual instruments, including cannons, car horns, anvils, typewriters and salad bowls. All have featured in concert performances over the last two hundred years, but who plays them? With the help of two leading British percussion players, Mick Doran and Neil Percy, Rainer explores the soundscape that can conjured up by bowing a cymbal, rubbing a plastic cup on a gong or hitting a car suspension spring with a hammer.
