Apparently, it's not much fun raging against the machine all by one's self. 

So, in the spirit of unified revolution-sparking, the pioneering Los Angeles quartet Rage Against the Machine is reuniting to coheadline the 2007 Coachella Valley Music and Arts Festival Apr. 27-29 in Indio, California. 

Frontman Zack de la Rocha, guitarist Tom Morello, bassist Tim Commerford and drummer Brad Wilk haven't shared a stage since September 2000. The following month, de la Rocha announced he had split from the group, saying that although he was quite proud of what they had accomplished, Rage's "decision-making process" had "completely failed." 

The dreadlocked musician-activist has kept a far lower profile than his former bandmates, who joined up with ex-Soundgarden leader Chris Cornell to form Audioslave. Instead, de la Rocha has kept busy recording tracks with the likes of DJ Shadow, Trent Reznor and British act Reprazent, and, although rumors of a solo album haven't come to fruition yet, his tune "We Want It All" showed up on the Songs and Artists that Inspired "Fahrenheit 9/11" soundtrack. 

While there's no word on whether the Coachella gathering will lead to more joint appearances, a single line on de la Rocha's Website, which is currently under construction, reads, "Rage Reunion, yea!" A simple sentiment, yet one that pretty much says it all as far as the band's fans are concerned. 

"You cannot understate their influence on where music went after them," Goldenvoice promoter Bill Fold, who's helping to produce this year's Coachella, told the Riverside Press-Enterprise. "Their sound as well as their message has a lot of deep-rooted meaning for a lot of musicians and fans...This is huge." 

This year marks the first time the increasingly popular music fest in the SoCal desert has been spread out over three days. Rage, which headlined the first Coachella back in 1999, will top the bill on Sunday, Apr. 29.  

The main stage will also play host to repeat headliners Björk (2002) on Friday and Red Hot Chili Peppers (2003) on Saturday.  

Also letting bygones be bygones for at least one night this year are the Australia-based showmen of Crowded House, who haven't performed live since 1996, and Scottish alt-rockers the Jesus and Mary Chain, who haven't appeared together since a messy gig at L.A.'s House of Blues in 1998, after which guitarist William Reid left the band; the remaining members went their separate ways the following year. 

Coachella, which continues to prove that tens of thousands of music lovers can still coexist in one field (sorry, Woodstock '99), has laid claim to multiple high-profile reunions over the years, including the hyped returns of Jane's Addiction in 2001, Siouxsie & the Banshees in '02, Iggy Pop and the Stooges in '03, the Pixies in '04 and Gang of Four and New Order in '05. 

Known for its eclectic something-for-everyone lineups, Coachella's recent offerings—in addition to up-and-comers and indie faves such as She Wants Revenge, TV on the Radio, My Morning Jacket, Bloc Party, Wolfmother and Art Brut —have included Madonna, Kanye West, Radiohead, the Cure, Beck, Nine Inch Nails, Coldplay and Weezer.

And this year will offer no less of a smorgasbord of genres, performance styles and levels of fame.

In addition to the Icelandic stylings of Björk, the crowd-pleasing stadium rock of the Red Hot Chili Peppers and the political musings of Rage Against the Machine, visitors to the Empire Polo Field this year can also check out sets from Interpol, Arctic Monkeys, Sonic Youth, Rufus Wainright, DJ Shadow, Nickel Creek, We Are Scientists, Arcade Fire, the Decemberists, Travis, the New Pornographers, Ozomatli, Regina Spektor, Kings of Leon, Ghostface Killah, Fountains of Wayne, Manu Chao, Air, Willie Nelson, Paul Van Dyk, the Roots, Kaiser Chiefs, Damien Rice, Placebo, Lily Allen, Amos Lee and José González.
