Looks vaguely like he's waiting to squash an ant that's soon to crawl out from under his shoe. You can't smash a bass like that: it's still almost perpendicular to the floor and he's already blown all the power he'd create moving his body to the ground. What's he gonna do, flick his wrists to bring it down on the floor?
most famous rock pic? excuse me... the quality is horrible. you don't even need to look closely to know that it's pixelated. there are many better pics of them... fsck with epicness. it's a cover of London Calling and Rolling Stones magazine put it on the 500 Best Rock Album bla bla bla.... if that's what you called epic then go ahead and keep voting it... i want a good quality (the higher the better) picture that will show how awesome all members of The Clash are, not just pixelated one man show. if you still think this is a great pic, please make yourself useful and upload a much better quality. (PS: gritty =/= pixelated)
