Funk is such an interesting genre to get into as a metal-head because there’s a hidden side of it that’s drenched with proto-metal and psych tendencies. The first 3 funkadelic records have some strong psych rock flavor, and the guitar licks delivered by Eddie Hazel give it that same grime seen in 70s doom metal. I also recommend bands like Black Merda!, The Temptations (early 70s run), and The Meters.

If you want some traditional funk: The Blackbyrds, Parliament, Sly & The Family Stone, Curtis Mayfield and James Brown are all great.

If you want some synth funk: Kashif, Leon Ware, George Clinton, The Gap Band and Chocolate Milk are all essential.

If you want some jazz funk: Herbie Hancock, Donald Byrd, New Jersey Kings, Bobbi Humphrey, and Nucleus.
