Most people assume that Dinosaur Jr. is essentially a J Mascis moniker, and that's certainly been the case for most of the band's career. But You're Living All Over Me and Bug—arguably the two most relevant Dinosaur Jr. albums—are great at least partially due to Lou Barlow's unmistakable influence (or more specifically, the polarity that existed between Mascis and Barlow). If I had to make the laughably disproportionate Lennon/McCartney comparison, I'd say that Mascis is probably Paul: As his monopolistic hold over the group tightened to an unbearable degree, Barlow left, concentrating on the far weirder, genuinely more interesting and emotionally impactful Sebadoh. 1993's Bubble and Scrape is a particular high-water mark, and "Soul and Fire" is so painful I can't even listen to it anymore. Meanwhile, Dinosaur Jr. released Where You Been, which I guess was sort of like J's Band on the Run. MORGAN TROPER Also see My, What a Busy Week!
