New dates continue to trickle out for Beastie Boys [ tickets ]' upcoming North American tour, with new confirmed dates announced for the Los Angeles, Philadelphia and Atlanta areas.

The trio also added a second San Francisco show to its schedule after its first show sold out; details are in the itinerary below.

Tickets for the four new shows will hit the market on Saturday and Sunday (8/14-15), and various ticket pre-sales are being offered before the general on-sale. Information is available at the group's website.

The New York-bred hip-hop act is backing its new album, "To the 5 Boroughs," which hit stores in June and debuted at No. 1 on The Billboard 200 album chart. It has since been certified platinum by the Recording Industry Association of America, signifying more than a million units shipped. The album--which features the single "Ch-Check it Out"--is the trio's first since 1998's "Hello Nasty."

Beastie Boys--along with Green Day, Kid Rock, Pixies, Sonic Youth, A Tribe Called Quest and many others--are also among the dozens of acts that will appear at this fall's Voodoo Music Experience in New Orleans.
