We know there will definitely by a Rachel Ray party, Fader Fort and Spin party (happening on March 19 at Stubb's BBQ and featuring Courtney Love and Hole)...but we have yet to hear who the BIG performers will be at most of this year's parties(and who all will be hosting them. Perez? You coming back?).

Kirsten from KLBG posted a blog today that says they got confirmation that the Stone Temple Pilots will preview their new LP with an appearance in Austin(Austin 360 also posted something about this). Kirsten also says Muse will perform(they are playing in Dallas March 17 and Houston on March 18) and hints that Soundgarden and Mötley Crüe may play as well.

And, my big scoop is that I hear Live Nation will host Justin Timberlake! Let's hope that's true.

Heard any other juicy details? Please pass them on.
