How about this for a left-of-field, off the wall 'gimmick' for the next tour ?
Concentrate on the fucking music. Nothing else
This other bollocks has been done to death. Theyve proved they do all that better than anyone else. So, its time to move on and has been for some time.
Now, since they're known as the 'greatest rock n roll band in the world' after all, how about proving (or at least trying to) that they can do THAT better than anyone else as well. Ideally, while there are still enough people around who can remember them for music as opposed to pyrotechnics.
Leave the cartoon stuff to bands who need to have gimmicks to pad their shows out to disguise the fact that they dont have the songs.
I deliberately passed on U2 this tour for two reasons - their new album was shit and the reports about their stage show just screamed "self indulgent wankery". Almost everyone I knew who went to see them came back raving about how spectacular it was. Hardly anyone commented on the music, which convinced me I'd made the right decision.
I sure as hell don't want the same scenario for the Stones.
