My favorite performance by Van Halen, the whole band is firing on all cylinders, in the prime of their career, but Eddie is especially incredible.
This song always motivates me, and the guitar on it is aggressive, cool, crunchy, technical, and fun all in one song, a combination nobody really pulls off in the way Eddie did, to me. Way better than Eruption, Jump or any of the other great songs EVH played IMO.
I watch this and imagine what it must have felt like for Eddie the first time he went on stage to perform this in front of a huge crowd, knowing the audience expected great things from him as a guitarist already and he was going to blow them away with some knew style even better than what they'd heard from him before.
