Here we are again! It's time to tell your boss that you'll be using all that saved-up vacation time to take a few days off in June; it's time to figure out who's car you'll be inhabiting for the better part of a week; it's time to figure out how the hell you're going to sneak three ounces of mushrooms past security at the festival gate. Today is the day on which Bonnaroo Music and Arts Festival 2010's lineup is finally released. This time around, the festival promoters have decided to make the unveiling a day-long event, announcing a few acts every hour. We will be updating the lineup regularly until the entire roster has been made available. So far, it looks like Roo 2010 will stay with the long established formula of mixing high-profile indie acts with a handful (or three) jam-esque bands. As we (sorta) predicted about a week ago, Weezer, Neon Indian and Phoenix will be sharing the bill with the likes of Jeff Beck, Norah Jones and Medeski, Martin and Wood. Comedy legend Steve Martin will also be on hand with his band the Steep Canyon Rangers, which is sure to be a treat, in and of itself.

Here are the performers announced so far! More additions will be made to the initial line-up as the festival approaches; we will be sure to keep you in the loop! For now, enjoy the (mostly) complete 2010 Bonnaroo Music and Arts Festival, headlined by Stevie Wonder, Jay-Z and Dave Matthews Band.
