When Dinosaur Jr played last time it was their reunion tour, Lou had just came back after well over 10 years and the original (and definatley best) line up was back together. I suppose people were expecting them to have a big impact on the music scene and thats why they were futher up the bil, that was in 05 right?
Well now they have been touring around pretty much non stop (I've seen them a few times and met them, they are amazing live and one of the loudest bands ive seen!) they have recorded a new album which I don't think sold amazingly well either so I guess they just aren't seen as the big deal that they should be.
It's ashame because people don't know what they are missing.
