I went last year. Actually I attended very few official SXSW events. (I did not buy a wristband and wouldn't pay hundreds of bucks for the badge.)
But I won't hesitate to say I had a whole lotta fun. Saw bands like The Gories, Kid Congo Powers, Thee Oh Sees and went to a couple of Saustex Records events and saw The Hickoids, The Grannies, Glambilly, Pinata Protest.
As some of you know, I'm a country fan, so I spent part of my time seeing acts like Ray Wylie Hubbard, The Waco Brothers, Calamity Cubes, Hellbound Glory, James Hand, etc.
And I saw a great modern soulster, JC Brooks & The Uptown Sound. (But I don't think Chuck Berry was there. I did see Little Richard there a few years ago and Carl Perkins a few years before that.)
If anyone gives a flying hoot, blogged it all HERE.
