Re: Dave Abbruzzese
Obviously he was in the band during their prime so it is no surprise to me that people hail his influence on them. Personally though, I always thought his groove was a bit too slippery per se and I felt like a lot of what he did was a bit much for Pearl Jam. I wouldn't call it over playing per se, not necessary. Especially his splashing away at the cymbals and his ride/hat combination performances. It really just comes down to his feel though.
Matt Chamberlain, though only in the Alive video, was the PJ drummer for me and Dave A. has him to thank for his career.
