Hmm, I voted for Lou Barlow he does some great melodic stuff on the 1st two records and some neat fills. I don’t mind him on the Dinosaur records but I REALLY REALLY can’t listen to his Sebadoh stuff anymore… They used to be my favourite band but I guess I burned them out and sold all his records… 
EDIT: Both times I saw J & The Fog Watt carried himself off admirably though.
