The album that revolutionized the 70's and changed guitar playing forever. This album has everything; hit songs, the greatest guitar playing (up to that point in time), and no "filler" tracks on the entire album. It also features the greatest cover song of all-time "You Really Got Me". I was too young when the album came out, but I have seen interviews with muscians at the time and all they could say about hearing Van Halen for the first time was "What the hell is he playing and how is he getting that sound?". This album is one of the best selling albums of all-time and it definitely set the tone for guitar players that came after Eddie.
