One of the greatest indie rock bands to date. Led by J. Mascis, one of the best guitarists, Originally with Lou Barlow(Sebadoh, Folk Implossion, etc) and Murph. Both of whom have gone on to do other things, and now the band is pretty much rotating except for J.

On a side note, all their records(as far as I've been told) are completely instrumented by J. which is one reason most band members don't stick around to long.
