Three days, eight stages, 130 bands, one portable.

Sony is setting the Playstation Portable to be the portable gaming device of Lollapalooza. Starting today, PSP owners can hop on over to the official PSP site to download a ton of palooza music, trailers, wallpapers and info.

As of this afternoon six trailers, 21 wallpapers and nine music sets were on the North American site, under the PSP Central tab.

In the weeks leading up to the Aug. 4 concert in Chicago, the site will add the artist schedules for all eight stages and a venue map. And if you bring your PSP with you to the concert (and it doesn't get stolen/broken), you can use it to enter contests going on during the event.

If you weren't going to Lallapalooza, you can head over to Playstation's site to enter a sweepstakes for a chance to win a trip for two to the show as well as a PSP and some games. Brian Crecente
