First, is it contrabass or contra bass? I would think contra bass since you can't do contraalto,(my spell checker says contralto is okay) perhaps contra-bass and contra-alto? Anthony Braxton is one. He has a ton of recordings so if anyone can steer me towards the tracks with contra-bass or contra-alto I would appreciate it.:-D http://www.youtube.com/watch?v=FUUQqpudBZ0 He does a lot of squawking on this one but it is interesting to see how he holds it. I don't feel comfortable playing a paperclip with a strap and no peg. It would be nice to hear someone play the contra bass (or alto) melodically.
