LugRadio Live 2008 USA (previously mentioned; register here) is looking to feature CC-licensed music at the conference:

At LugRadio Live in the UK, we traditionally play a lot of rock music in-between talks – it keeps the atmosphere loose and fun. With LugRadio Live USA 2008 on the horizon, and well aware of the dictatorship that is the RIAA, I am keen to find a collection of good rock and metal that is suitable for legal public performance at LugRadio Live USA 2008.

Some places to look. I’d recommend some sexy French punk rock.
