Last Friday, Pitchfork.com revealed the first batch of hip-as-shit bands that will be performing at the 2010 edition of the Pitchfork Music Festival, to be held July 16-18 at Chicago’s Union Park. Modest Mouse headlines on Friday, LCD Soundsystem and Raekwon appear on Saturday, and Sunday’s bill features Pavement as well as St. Vincent, Lightning Bolt, Cass McCombs, Here We Go Magic and Sleigh Bells. More bands will be added in the coming weeks; to get your tickets now ($40 single-day tickets, $90 three-day passes), click here.

And today, organizers have announced the first batch of confirmed artists for the ninth annual Bonnaroo Music & Arts Festival, which is held June 10-13 on a big old plot of land in Manchester, Tenn. Among the current highlights are The Flaming Lips covering Dark Side of the Moon (likely with Stardeath and White Dwarfs, the band that originally collaborated with the Lips on the album), Phoenix, Weezer, OK Go (pictured, and in my humble but well-informed opinion, responsible for the best album of 2010 so far), Jeff Beck, John Fogerty, Norah Jones, Medeski Martin & Wood, Chromeo with guest Daryl Hall (re-living their Live from Daryl’s House episode on stage), Regina Spektor, Isis, Mayer Hawthorne and the County, The Black Keys, The Constellations and some others. More will be announced as the fest date nears. General admission tickets at $209.50 and $224.50 have already sold out; the remaining tickets are priced at $234.50, then $249.50 once the batch at the former price sells out. There’s also other ticket packages available as well as payment plans for the economically strapped. Click here to secure your tickets.
