personally i thought the stone Bigger Bang tour was great. and you can't for get their Steel Wheels tour and the giant inflatable penises. a precursor to the Lemon?lol
For me it has to be Elevation, the simplicity compared to previous tours and the way when you were inside the heart it made it feel like an intimate show. Almost forgot about the 1000's outside the heart until you were reminded when Streets was played and the whole arena was bathed in white light.
