Along with other bands that were around for the first Lallapalooza, this years 'event' will also feature newer acts, such as Flaming Lips, Ween, Broken Social Scene, and that 'hot new group all the kids love today' ...Blues Traveler!
All joking aside, there really ARE newer groups and artists thrown into the mix. In fact, there's gonna be 130 different acts at this years festival.
Along with the 'old schoolers', you'll get to see Kayne West, who I really don't see the reason for him to be playing an alt-concert where the most common color you'll see worn by the attendees will be the pale white of their skin from not getting enought sunlight.
For the hip-hop fans out there, West will be playing along side Common and Matisyahu
If interested, the link above gives the full list, without the jokes.
The CEO of Universal says the reason the record industry never bothered in online music was because no one knew how to do it. http://nymag.com/daily/entertainment/2007/11/universal_music_ceo_doug_morris.
