If you've never seen this fictional 1988 "student film" of Rick Rubin's then you must ASAP, especially If you are a fan of Run-DMC, The Beastie Boys, Rick Rubin, or Def Jam during the early years, (there's also a classic Junk Yard band performance at a backyard party, and Slick Rick to name a few.)
I have no idea how long Tougher Than Leather will last on YouTube, and it's not on DVD as far as I know, but it's a classic, tasteless epic, that needs to be seen to be believed. It actually played in theaters to riots. Some great cameo's too (Rick's dad, Russell Simmons dad [RIP] who put in two of the greatest performances in the film, to name a few, besides the infamous Richard Edson, and Lois Ayres, George Drakoulias and I running down the street for a hot second at around the one hour mark too).
If you live in lower Manhattan you may also recognize some of the locations all within a walk from the original Def Jam offices at 298 Elizabeth street. I shot some stills on the film that I'll add below (the poster up top was based on one of my photos as well.)
Enjoy, I know you will. I'm re-watching, after not seeing it for over 20 years, as i'm putting together this post, and it's blowing my mind.
