Sci-fi-storytelling prog-rockers Coheed and Cambria performed in Sydney, Australia in April, and now, thanks to Moshcam, the entire professionally-shot concert is on YouTube. Few other bands (probably none) can claim to have been telling the continuing saga of people on alien worlds over the course of their entire career as a band. It's certainly something different. And they play pretty impressively too.
You can get Coheed and Cambria's latest album, The Afterman: Descension on iTunes.
