My son Alex, who plays under the name Alexander Thomas (“myspace page”:http://www.myspace.com/alexanderthomasmusic) , plays the “theremin”:http://en.wikipedia.org/wiki/Theremin (and then puts the output through various electronic boxes). As well as playing various gigs round the country, he’s also just had “a session on BBC Radio Bristol’s BBC Bristol Introducing programme”:http://www.bbc.co.uk/programmes/p001mhrq . He plays three pieces as well as talking a little bit about the instrument (the first is just after 30 minutes in). The session should be available for the next seven days.
