Raekwon and Ghostface Killah have announced a documentary about Raekwon's 1995 debut solo album, Only Built 4 Cuban Linx. The pair announced the news at Sundance Film Festival, premiering a teaser trailer of the film for some lucky audiences.

Called The Purple Tape Files, there is no news of its content or release date, so all we can do is sit back and wait for the pair to say more. Raekwon did announce the documentary on Twitter though, presumably after the showing of the trailer – maybe he'll say more.

Did you see the trailer at Sundance? Do you know anybody who did? Tell us about it!
