J Mascis was another artist I was looking forward to seeing here at SXSW. I've never seen him play live and have been a Dinosaur Jr. fan for quite sometime. It's been a while since I've listened to the Dinosaur Jr. material, so I had a listen to "Where You Been" and "Martin and Me" a couple weeks ago. "Where You Been" is a great album that I think is still relevant today. It's definitely a lot better than most of the crap rock that is out these days.
J performed about 3 or 4 songs that included "Get Me" then went into an instrumental that was played over a loop. I couldn't tell you how long the instrumental was, several minutes maybe, but it was completely captivating.
