All links point to the 2005 SXSW Showcasing Artist page for the artist mentioned, except in the cases where I could not find a page (which probably means that the MP3 is located in the “add-on” batch of 20 songs).
The music ranges from bluegrass (Runaway Planet), dub (Sub Oslo), Americana, pure pop, punk and loads of decent acoustic tracks. There are also a small handful of bands seeking to revive the glam-punk of The Boys (Ends, Bones, Real Heroes) and some good electronica tracks. If you have been listening to my podcasts you will have already have heard a third of these tracks; I recommend you get the rest as well while you can (this batch of MP3s will probably be taken offline when the 2006 festival comes along).
A dozen or so artists are not listed simply because I already had the songs. So no Jawbone or Kings of Convenience in the list.
Sturgeons Law applies; this is the top 5%.
I listened to every one of the 750+ tracks and brought the list down to those below. Should you prefer to download all 750 tracks there is a couple of torrent feeds at SXSW’s Fest4Pod.
I’ll see if I can get time later to include direct links for the MP3s; but for now you will have to go each SXSW artist page to get the MP3s.
