A few pointers:
1/ He doesn't want to be too genre-specific...ie nothing that refers to just one kind of music.
2/ His initials are AMS so anything that incoporates that could be good...
3/ His mates have a studio called Offshore which we both think is quite cool, so perhaps a non-music-related-but-still-cool-random-word name?
4/ The studio is built in a converted garage, in South Wales (near Cardiff)
5/ He is a drummer so perhaps something drum-related...? (But like I said, without being too genre-specific).
It's a tough one! Any suggestions gratefully received, I will ensure that if any of them get picked a suitable prize will be issued
