The film is a fictionalized account of the early days of Def Jam Recordings and Rush Management. Rick Rubin and almost all of the musical acts played themselves in the movie. Russell Walker, the character played by Blair Underwood, was based on Russell Simmons, who appeared in the film as the club owner who said, "Let's get these kids on stage," just before the infamous Run's House scene.
The soundtrack of the movie, released on Warner Bros. Records, was released on CD once--in Japan--and only 1,000 copies were made, until 2014, when it was licensed to Perseverance Records, a label that specializes in rare movie soundtrack albums. The reissue includes the two bonus tracks that were on the Japanese CD.
The original concept of Krush Groove was a concert documentary of the original Fresh Fest, one of the first hip-hop concert-arena tours, but Russell Simmons convinced producers Michael Schultz and Doug McHenry to produce an original feature film instead.
