One artist/group I think has been unfairly forgotten is The Jimmy Castor Bunch. They made some iconic hits of 70s funk music that I never hear anyone talking about in my circles!
If you listen to a lot of hip-hop, you’ll PROBABLY recognize the sample at the beginning of The Troglodyte (Cave Man) “what we’re going to do is go back, way back: back into time”
But they had a bunch of hits back in the 70s!
One of them, is a sequel to the above song: The Bertha Butt Boogie
They also made a bunch of songs about monsters (Dracula, King Kong) and sci-fi concepts (Space Age) that are tons of fun! I found out about ’em years ago by buying cheap 45s from bins with titles that seemed amusing and was surprised to find that they’re both really good and were once very popular! But I think Jimmy Castor’s been largely forgotten: looking for CD reissues of classic albums, I could only find Japanese releases and compilations.
