For those that don’t know, one of Hip-Hop’s unseen hands in the late 1980s was a Queens, New York engineer/producer named Paul “C” McKasty. Large Professor, who came up with Paul (both with works uncredited) on albums by Eric B. & Rakim and Kool G. Rap & DJ Polo, named his Paul Sea production company as a part dedication to the man who was tragically murdered in 1989—a shooting that has never been solved.

Filmmaker Pritt Kalso compiled footage since the ’90s on Paul C., and in a way, Large Pro. Rakim, Ced Gee, TR Love, Pharoahe Monch, O.C., Cassanova Rud, C.J. Moore, Mikey D, Dr. Butcher, and plenty of others are among who comment on Paul’s impact. This video gives you visuals behind the under-covered Hip-Hop legends, and shows the places and times. This is worth every bit of your 20 minutes, and will immediately make you pull out cuts that Paul had a hand in (see this list).

There’s two parts which are currently not-embeddable, with a third we’ll add soon. R.I.P. to Paul “C” McKasty, your name, impact, and sonic genius lives on.

Here’s a dabble of the Paul C. sound, courtesy of the great Stezo:
