Although always as loud as god, it was easy to convince yourself the music of Dinosaur Jr was far more passive than aggressive. This myth exploded in a hail of flaming toads in the spring of 1989, when the band’s original trio line-up burst like a ripe sac of pus. In the intervening years there have been various versions of Dinosaur Jr, several of which made use of ur-drummer, Murph; but none of them included prodigal bassist, Lou Barlow. Until now. Until Beyond.
