(dunno if linking these are allowed, if not, sorry!)
this is a link to a 2.5gb file, with one track by every band who showcased at SXSW this year. 711 tracks, I've been slowly working my way through it and there are moments of brilliance throughout. Lots of stuff you'll have heard of, loads more stuff you won't have. Think of it as gigantic DiS Mixtape with a few crappy C&W tunes included... There's a tracklisting at the link too.
Current favourites are Scissors For Lefty, Shout Out Out Out, The.Story.Of, Aberdeen City and Beans (with Holy Fuck)
