Oceansize, Feed to Feed -- jesus christ these guys are good, probably a little too ambient/chill for the current Porcupine Tree crowd, but they do wallop once in a while (probably proportionately less than PT). Also more indie-sounding. And British. Which in my book is a good thing. Lead vocalist sounds somewhere between Joe Jackson and Eddie Vedder. In some ways, I like them better than PT.
It's too bad this is limited, I'll try to get a copy, but I'm not paying more than retail for it. Especially if the band doesn't see the extra dosh.
Oh, and what it is: get this -- 3 DVD/4 CD souvenir of the event of a series of live concerts in which, to celebrate their birthday, they played their entire catalog. So they didn't just play entire albums, they played all of their entire albums...er...all of their albums in their entirety, that is.
EDIT: Plus, they funny:
Here, gib a listen.
