Led Zeppelin were the progenitors of heavy metal and hard rock, and their sound was largely the product of Page's input as a producer and musician. The band's individualistic style drew from a wide variety of influences. They performed on multiple record-breaking concert tours, which also earned them a reputation for excess. Although they remained commercially and critically successful, in the later 1970s, the band's output and touring schedule were limited by the personal difficulties of the members.
