We've been waiting for word from Live Nation about their two-day festival on Harriet Island for a while now, and speculation has mostly centered on what kind of festival this will be. With today's announcement of the freshly branded River's Edge Music Festival, it appears that there is no clear theme or genre tying together the event; rather, an utterly random mash-up of commercially popular rock, hard rock, and dance artists will perform on the island on June 23 and 24.

Headliners for the festival are Tool (performing on Saturday the 23rd) and Dave Matthews Band (on the 24th), with support acts ranging from last year's SoundTown headliners the Flaming Lips to Tool frontman Maynard James Keenan's side project Puscifer. A handful of local artists are also on the bill, with Polica and Motion City Soundtrack each near the top of the billing along with Quietdrive and relative newcomers the Rope.

Here's the complete lineup (so far) for River's Edge:

Dave Matthews Band, Tool, The Flaming Lips, Brand New, Polica, Motion City Soundtrack, Puscifer, Coheed & Cambria, Diplo, Scissor Sisters, Datsik, MuteMath, Delta Spirit, Blaqstarr, Kinky, Mexican Institute of Sound, Civil Twilight, Quietdrive, An Horse, Gardens & Villa, AM & Shawn Lee, The Whigs, Hey Rosetta!, K-Flay, Yawn, Kids These Days, Yuna, The Rope

Two-day passes are $99 and go on sale Friday, April 13.

At a press conference today, mayor Chris Coleman and Live Nation said that there will be two historically referential stages, one named Ohage (after Dr. Justus Ohage, St. Paul's commissioner of health in the late 1800s and early 1900s who purchased and later donated Harriet Island to the city), and one named Bishop (for the island's namesake, school teacher Harriet Bishop), in addition to a third DJ stage. The total capacity for the event is 40,000, and each night has a strict end time of 10 p.m. More acts are expected to be added in the coming weeks.

The city also revealed that Live Nation will underwrite their annual 4th of July on Harriet Island and are partnering with the Children's Cancer Research Fund. With all of AEG's recent promises that they are dedicating their resources to developing downtown Minneapolis, it seems that Live Nation has their sights set squarely on St. Paul. It will be interesting watching the Twin Cities, which have long been fiercely independent playgrounds for concert promoters, work within and around these corporate strongholds.
