What are the bands that defined your generation

Have reached the losing more friends then gaining them point of life. Another funeral today got me nostalgic for music that defines us. Will start out with a classic i discovered the opposite sex with. LOL. This is a very long 17 min. unbelievable cut with the best drum solo ever. If nothing else watch the beginning and end. Please post your video clips that define you or your generation.

Thanks
