Here are some live clips that seriously kicks ass and defines certain aspects of live music for me:
The blues: The first one is a live clip from French television with Jon Spencer Blues Explosion. I don't know diddely squatt about what good blues is supposed to be but this guy is so intense that he scares the bleep out of me. It's a total kickass performance, nut cracking experience. The band plays in a total trance at the end! It's two songs in a row so the clip is a bit long but worth watching. Who the bleep is Clapton? :

Trash metall: Next one is the total opposite of the first one. It's Megadeth performing Lucretzia at the Roskilde Festival (which I didn't go to, I honestly regret it today). This is a punch in the face with razor sharp trash metall. Megadeth was at it's absolute best. The song is not that complex but everything is delivered with ultra sharp attitude and precision which makes it lethal. No stupid tattoos, no spandex, no posing, just trash metall up your ass. Dave Mustaine delivers the best metall rythm guitar in the world here, sorry Hetfield, you have always been second to Mustaine:

Rock'n'roll: The last one is a classic. The Cramps plays at the Napa State Mental Hospital. This must be one of the coolest clips ever, you tell me who's in the band and who's a patient. Everyone just goes gazonkas! Enjoy:
