Zeppelin goes diverse in many albums. For me II, IV, and Houses of Holy are my favorite. But II really just shows the bluesy hard rock type that i love from Zeppelin. Aerosmith, get pre breakup stuff. The first three post break up albums have parts of of greatness. Nine lives and Just Push Play are really bad. But A night in the Ruts, Toys in the Attic, and Rocks are probably among the top 20 off my fav albums of all time.
