Here's a photo I took at a sound check at Madison Square Garden in 2006. First person to correctly name the drummer in the pic gets a shout out on this blog. Leave a comment below.
ANSWER: It's Nick Mason at a sound check for a Roger Waters show . "Anonymous" had it right. If you look closely at the design on the drums it is from the Hipgnosis-designed cover art for Pink Floyd's "Dark Side Of The Moon".
