lukin,
Fishman is a monster!!! ( I love Phish, listening to "Rift" as I type this)
Lars is a very unique drummer. He does things nobody else does in terms of fill placement.
There was a project a few years back that was basically a tribute to Mr. Rich. Various drummers playing Rich pieces. The story coming from that was Peart had the hardest time with what he was supposed to do. It seems if he doesn't come up with the groove, he has a hard time. It took multiple takes to get his parts right were most of the other performers nailed on the first or second take. The producers were very inumpressed with Mr Peart.
MANY drummers right lyrics and even sing. Gil Moore of Triumph comes to mind, as well as Don Henley (Eagles) Kelly Keggie (Night Ranger). Hell I even wrote lyrics and sang a few tunes in a band I was in years back. Not all the difficult. I dont mean to piss on the Peart lovers cheerios but he isnt all that much better than anyone else mentioned here. He was lucky enough to be in RUSH were they let him just do whatever. There are a lot of drummers with skills as good or better that are in bands/projects that dont allow them to go off like he did. Hell I bet most of you dont know that Steve Smith of Journey fame is one of the best jazz players around today. He is freakin amazing. Ya never would have guessed by what he did with Journey.
