Getting the band back together is about more than just nostalgia.

When it comes to big bands, it means big sales, big crowds and big money.

An artist's popularity and cultural relevance can continue to grow even if his or her band is no longer recording or performing. For some bands, that means playing to larger crowds than it ever has before. A reunion can satisfy the interest of fans, produce big revenue and even revive a band's waning popularity.

Maha Music Festival has specifically gone after bands that were on hiatus or that rarely tour, taking advantage of the popularity of reunions. Organizers pursued Superchunk, Guided By Voices, Desaparecidos and Garbage for those reasons.

This year's Maha, today at Stinson Park at Aksarben Village, features Desaparecidos, not together for years until just recently, as well as Garbage, which was on hiatus for seven years.

Before this year's festival, Desaparecidos played a 2010 show in Omaha, but otherwise had been disbanded for a decade.
