Page wrote most of Led Zeppelin's music, particularly early in their career, while Plant generally supplied the lyrics. Jones' keyboard-based compositions later became central to the group's catalogue, which featured increasing experimentation. The latter half of their career saw a series of record-breaking tours that earned the group a reputation for excess and debauchery. Although they remained commercially and critically successful, their output and touring schedule were limited during the late 1970s, and the group disbanded following Bonham's death from alcohol-related asphyxia in 1980. In the decades that followed, the surviving members sporadically collaborated and participated in one-off Led Zeppelin reunions. The most successful of these was the 2007 Ahmet Ertegun Tribute Concert in London, with Jason Bonham taking his late father's place behind the drums.
