I have seen Cozy Powell 2 times, Bill Ward, Mel Gaynor zillions of times, Marco Minnemann, Joe Travers and have seen this chap (Gavin Harrison) 2 times in the last year, of the drummers i have seen live, none of them have had as much influence over the sound as Gavin Harrison, a genius behind the cans, The Pineapple Thief tour was marketed as the The Pineapple Thief, featuring Gavin Harrison, a drummer I would have liked to have seen in his prime was Stewart Copeland, so much rhythm, talking to covers band around the valleys, you very rarely hear rush covers, it's not because of the work by Geddy Lee and Alex Lifeson, it's because of Neil Peart.
