Personally, struggle to see much beyond/since The Clash and other (although slightly lesser) bands of their day. Not heard much with that sort of energy and passion since. Odd exception such as Foo Fighters. Red Hot Chili Peppers, Rage Against The Machine, then Stone Roses, Happy Mondays etc.
Did go to see ColdPlay a few years back to keep the missus happy. I remember a guy in the loos raving about them and saying to me really enthusiastically " It doesn't get much better than this, does it?" (He was talking about the gig!). He looked really shocked and slightly offended when I said "They're OK, but they're not exactly Stiff Little Fingers, are they?" It just wasn't the same!
Maybe I'm just an old fart?!
