Dead Prez are celebrating the 10-year anniversary of their classic debut record 'Let's Get Free' the best way they know how: with a new mixtape. The free record, an installment of DJ Drama's game-controlling 'Gangsta Grillz' series, should pay tribute to the classic rhymes of 2000 Dead Prez while providing a unique new look for younger fans that might follow Drama's exploits but have yet to really experience what the DP are all about. Titled 'Turn off the Radio Vol. 4: Revolutionary but Gangsta Grillz,' the tape will hit the Internet on June 22.

"We wanted to just capture that love for hip hop," said group member Stic.man. "To give the people something for the summer that we could let folks know we still here, we doing well and we still growing. The hunger is there, the creativity is there, the flows are there, and the message is there. This is one of my favorite albums in the 'Turn off the Radio' series."

The tape is a follow up to last year's DJ Green Lantern-helmed 'Turn off the Radio Vol. 3: Pulse of the People.' Initial leaks from the new work find Dead Prez spitting their trademark mix of militant and conscious rhymes over B.o.B's 'Nothing on You' and Drake's 'Over.'

Look for 'Revolutionary but Gangsta Grillz' at the Dead Prez website on June 22.
