Expanding on its "two-headed dog" re-launch in February, MTV2 is unveiling new long-form music content featuring artists Sum 41, Green Day and System of a Down, Billboard.biz has learned.

In addition to System of a Down's first televised concert on May 20 -- taped live at London's Astoria -- the network is developing a Sum 41 tour mockumentary, "Road to Ruin," highlighting the mischief of the group while on the road. An airdate is still being determined.

MTV2 will sponsor a 43-date Green Day tour in August, with footage shot by the members themselves to air with backstage highlights in future programming expected in September.

MTV2 will also introduce the "Sucker Free Concert Series" together with the House of Blues. Kicking off July 2, the shows will take place with a different hip-hop act every Saturday in July with stops in New York, New Orleans, Chicago and Los Angeles. Confirmed artists include Mike Jones, Trillville, Lil Scrappy and Da Back Wudz. The shows will be free to the public with unconfirmed airdates.
