Beastie Boys' Adam "Ad-Rock" Horowitz is set to perform at a benefit gig for an imprisoned Russian punk rock act in Brooklyn, N.Y., tonight (June 12). This marks the rapper's first appearance since bandmate and friend Adam "MCA" Yauch was tragically lost after a three-year battle with cancer last month (May 4).

The world is still reeling from the the unexpected passing of Adam Yauch, as, undoubtedly, are his fellow Beastie Boys. Even with Yauch's death still very fresh in everyone's memory, Ad-Rock will soldier on tonight for a cause that is very near and dear to his heart -- punk rock.

The Beastie Boy is reportedly set to perform at a benefit show for imprisoned Russian punk rock outfit P--sy Riot. Three of the band's members -- Maria Alekhina, Nadezhda Tolokonnikova and Ekaterina Samucevich -- are facing up to seven years in prison on charges of hooliganism for their alleged role in a demonstration against Russian president Vladimir Putin.

According to Rolling Stone, the show is set to take place tonight (June 12) at Death by Audio in Brooklyn, N.Y. and is being organized by the feminist art group Permanent Wave. The night's festivities include performances from Heliotropes, Shady Hawkins and TinVulva in addition to the appearance of Ad-Rock, who will serve as DJ for the event. Those who would like to attend will be able to gain admission with a minimum $7 donation, from which the proceeds will be put towards the legal defense fund for the members of P--sy Riot.
