I just love classic funk. Like 1968-1972. Pre-slap
All of those listed above plus JBs, Cymande, Mandrill and so many anonymous bands that did one or two tracks with fantastic basslines. A lot of your best music was ignored at home, but got rediscovered here by British DJs.
But the band I like best is Parliament/Funkadelic
Check this. Billy Nelson with an Ampeg Scroll bass. It is as much rock as funk. I reckon George Clinton is tripping.
