Coachella = April 25-27, 2008 — who will reunite?
Iggy Pop & The Stooges - Coachella 2003
In 2001, the festival organizers were having trouble attracting a major headlining band. Running out of time, they went to friend Perry Farrell, who reunited Jane's Addiction in order to headline that year's event. Since then, it has become somewhat of a Coachella tradition to reunite at least one band for each festival. Although the line between a hiatus and an actual breakup is somewhat blurry, a number of artists are considered to have been reunited at Coachella, or have played Coachella as one of their first major shows after a reunion. The following is a list of performers who reunited or made a big return at a Coachella festival.
Rage Against the Machine reunited after 7 years
Crowded House - Had reunited for a 12-month tour
The Jesus and Mary Chain
The Happy Mondays
Daft Punk - First U.S. performance since 1997

Cocteau Twins - Cancelled a month prior to the show
Iggy Pop & The Stooges
