Raekwon and Ghostface Killah have dropped the trailer for an upcoming documentary focused on the former’s seminal 1995 album Only Built 4 Cuban Linx…. The trailer for the film, called The Purple Tape Files, included cameos from Kendrick Lamar, Method Man and numerous other Wu-Tang Clan members who shared their thoughts about the project.

“It ushered in the alter egos, the aliases,” RZA says, while Lamar adds, “Still, to this day, it’s flows that you haven’t heard before, saying the most wild s—t.”

Many people referred to the LP as The Purple Album and Raekwon said the color purple was an intentional choice for the cover.

“I put myself into a serious mind frame,” Raekwon said. “A serious storytelling album. I had to make this product stand out…I knew that purple represents royalty, and that’s exactly what I was looking for,” he said.

Raekwon went on to talk about having to prove himself as a rapper in his own right. “We had to make a conscious decision,” he said. “Either we want to stay here and keep holding guns and want to run around playing this game, or did we want to go for the American dream and get on this rap s—t.”

Only Built 4 Cuban Linx… is considered one of the greatest rap albums of all time, and a mafioso rap masterpiece. By 2009, the album was certified platinum by the RIAA.
