Fronted by singer-songwriter/guitarist J Mascis, Dinosaur Jr formed in Massachusetts in 1984. Their emergence was a musical shot heard round the world as Mascis and company put the heroics of lead guitar back into the forefront of the indie rock realm. Amazingly, it was a revolutionary idea at the time. Post-punk and pre-grunge, they were an intense force to be reckoned with. "Where You Been", their second album for Sire, was originally released in 1993.
