Recently premiered at the Sundance Film Festival, a trailer has now been released for The Purple Tape Files. A crowd-funded documentary about the making of Raekwon’s 1995 album Only Built For Cuban Linx, the title refers to the original purple cassette which distinctively marked the record from anything else on the shelves. The trailer includes interviews with Raekwon, album co-host Ghostface, plus Wu-Tang members U-God and Method Man. Legendary producer Quincy Jones is also featured, as is rapper Nas who last year released Time Is Illmatic, a documentary about his own debut release. Check out the trailer here.
