is Lunascape, a European group with a lead singer who sounds like the second coming of Dolores O'Riordan of The Cranberries and looks like Claire Danes. I'm always amazed at the one-inch punch that those spritely European women produce with their voices.
You might also like Tristeza, a group that deserves a better classification than the "Alternative" label they've been given on iTunes. IMHO, they're 1/3 jazz, 1/3 techno and the rest a concoction of prog rock and ambient. Very cool and bordering on danceable.
The best investment I've ever made was a subscription to Echoes Online, a PRI radio show that expanded onto the web a couple years ago. It has turned me onto more cool new music than any conventional radio station ever has.
