There is nothing quite like a Dinosaur Jr. album. The best ones are always recognizable from the first notes. And even though J tries to trip us up by smearie been laughed out of the tree fort. The trio’s early shows were so full of sonic chaos, such a weird blend of aggression and catatonia that we all assumed they would flame out fast. But the joke was on us.The trio has taken everything they’ve learned from the various projects they tackled over the years, and poured it directly into their current mix. J’s guitar approaches some of its most unhinged playing here, but there’s a sense of instrumental control that matches the sweet murk of his vocals (not that he always remembers to exercise control on stage, but that’s another milieu). This is head-bobbing riff-romance at the apex. Lou’s basswork shows a lot more melodicism now as well, although his two songs on I Bet on Sky retain the jagged rhythmic edge that has so often marked his work. And Murph…well, he still pounds the drums as hard and as strongng “Don’t Pretend You Didn’t Know” with keyboards, it’s clear from the moment he starts his vocals that this is the one and only Dinosaur Jr., long reigning kings of Amherst, Massachusetts (and anywhere else they choose to hang their toques).
