I love all of those bands too! Back when I started playing in 1977 I was attracted to a lot of the funk bands of the day. A lot of great bass tracks on them. Some of my favorites to this day are:
Brothers Johnson - Strawberry Letter 23
Slave - Slide
Sun - Sun Is Here
Mass Production - Firecracker
T Connection - Do What You Wanna Do
Isaac Hayes - Don't Let Go
Roy Ayers - Freaky Deaky
Foxy - Get Off
Even some of the Disco
stuff was fun to play. I still loved the rock and roll mind you. I just had a wide variety of influences!
