When a reunited band just keeps … going, do you still call it a reunion? Dinosaur Jr. is set to release its third proper full-length since reforming the original line up in 2005. The new album, I Bet on Sky, is streaming now at NPR and comes out next Tuesday via Jagjaguwar. Similar to Mission of Burma’s post-reformation output, Dinosaur Jr. hasn’t embarrassed itself at all. In fact, each reunion album has bettered the one before it. Seeing the original trio back in 2007 was, well, “life-long dream” is a tad strong, but it was awesome nonetheless.
