Gearing up for an early-summer tour, Pearl Jam [ tickets ] will offer its fans exclusive "mobile bootlegs" of several songs from each performance along the road.

As the veteran rockers progress along the tour, the band's studio engineer will mix three songs on Verizon Wireless's mobile studio unit that will be accompanying the tour. Verizon customers with V CAST will then be able to download one of the songs for free, and will have the choice of purchasing the other two cuts.

Each free song will be available until the next show during the tour, which kicks off tonight (6/11) in West Palm Beach, FL. Customers will be able to access and purchase all three tracks from each show through the end of the tour, however. The songs can be downloaded as ringtones, ringback tones or complete songs. Full details are posted at Pearl Jam's website.

The 10-city outing includes a June 14 stop at Manchester, TN's Bonnaroo Festival, and concludes with a pair of shows in suburban Boston late in the month. Details are below.

Pearl Jam continues to tour behind its eighth and most recent studio album, a self-titled 2006 release, but the band reportedly has begun recording demos for a possible follow-up with producer Brendan O'Brien, who has worked with the group on several albums, most recently 1998's "Yield."

"It's really in its infant stages right now," guitarist Mike McCready told RollingStone.com last month. "We have about five ideas that have been worked on.

"Brendan is another set of ears that we respect, and he's going to give us a different way to go but I don't know what that is yet," he added.
