1984 1st Movie Demo of Music Editing Software - Analogue vs. Digital Mixing for Hip Hop DJs

From the 1984 film "Beat Street" - the son of Ossie Davis and Ruby Lee shows the daughter of Tommy Chong and Maxine Sneed how he mixes his music for his DJ gigs using old school equipment. Then she brings him to her university so Night of the Living Dead hero Duane Jones can demonstrate avant-garde computer mixing software. Real time transitory history!
