It's extremely unusual for a band on Rove Live to catch my attention. Actually they're mostly total shite. But The Cat Empire really grabbed me. Must grab their album when I have the money. In the meantime they're giving away the mp3 of the song they played. Reminds me a little of Supergroove, although lighter.
Also; their site is an example of Flash done well... at least in terms of usability and design.
