Can somebody name a bunch of many 70's funk, R&B/disco bands you know?

I am working on bass guitar and I really dig the bass sound in this type of music. Trouble is I just discovered it and not so familiar because I was a late 80's and early nineties child
I used to hate it when my dad played it but now I love it
I know who Lionel Richie is. I just couldnt remember the groups.
I know more about him than his daughter
