It's been 20 years since Dinosaur Jr.'s innovative You're Living All Over Me, a 34-minute blast of Neil Young-inspired guitar frenzy that blended punk with classic rock. Can this reunion album the first since 1988 with original bassist Lou Barlow live up to Living? Of course not. But it's still worth hearing, with J Mascis' guitar as blistering as ever and the group's considerable energy undiminished. Though too long at 50 minutes, Beyond is an often thrilling reminder of this essential band's heyday. B+
