NPR has streaming audio and a downloadable podcast of Blitzen's full set at SXSW in Austin this past Thursday. Here's the link.
I was lucky enough to be there for this, and I have to say it's one of the best shows I've seen. The crowd was super amazing and PUMPED for BT, the sound was great (our soundguy coincidentally first learned to do sound on that very soundboard), and the guys sounded really tight.
Special thanks to the fans who started chanting for BT patches after the show. You pretty much made my day.
Thank you Austin!
