Funkadelic and Parliament are two of my favorite funk bands Darth. Someone here mentioned the song Funk #49...this is not funk...it's hard rock by The James Gang (Joe Walsh), which I'm sure you're already aware of.
I own so many great Funk albums from the late 60's-70's.
The band Funkadelic were amazing, and Eddie Hazel is one of my favorite guitarists. His playing style was very much influenced by Jimi Hendrix. Ron Bykowski also played lead guitar for them...and he smokes as well!
Their albums, Maggot Brain, Free Your Mind & Your A** Will Follow, and America Eats it's Young were great examples of psychedelic funk...lots of cool fuzzy guitars and long jams.
By the 'Cosmic Slop' album, they had really become much more cohesive as a band, and had adopted a really cool funk/rock sound. The amazing lead guitar work of Eddie and Ron always took the forefront, with George Clinton's lyrical wit and humor not far behind. Bootsy Collins bass playing gave the band a great sound too, and his revolutionary technique/style was really starting to evolve around this time also.
These are some Funkadelic albums I know you'll enjoy:
Their first album (self titled) 1970
Free Your Mind...And Your A** Will Follow 1970
Maggot Brain 1971
America Eats Its Young 1972
Cosmic Slop 1973
Standing on the Verge of Getting It On 1974
Let's Take It to the Stage 1975
Parliament was another cool band, and featured George Clinton as well. The first Parliament album called 'Osmium' was released in 1970, and in my opinion is a funk/psych/rock masterpiece! Their second album was not released until 1974, and by that time their style had changed to the more typical 70's funk sound of the day...akin to Funkadelic.
Parliament featured many of the same members as Funkadelic, including Eddie Hazel and Bootsy Collins.
Here's a few other great Funk bands of the late 60s-70s.
As the 70's progressed, some of these bands began to verge on disco...so be careful! Though since you don't mind 'KC and the Sunshine Band'...this shouldn't bother you at all... LOL

You seemed to have developed a passion for 70s jazz fusion lately, and many bands/artists like Return to Forever, Deodato, Stanley Clarke, Weather Report, Alphonse Mouzon...and many others verged on funkiness too.
Check out Stanley Clark's album 'School Days'...I think you'll really enjoy that too...great funk grooves!
Edit - Now Playing: Funky Woman by 'Mahogany Rush'...definitely not a funk tune or band, but it's easy to see how someone might get confused, based on the title of the song...LOL
