Been listening to lots of Marvin Gaye and Funkadelic. I'd love to hear more recommendations.
if you want more newer stuff also check out Charles Bradley - Victim of Love
Aretha Franklin - I Never Loved a Man the Way that I Love You (earns its status as a classic)
Al Green - basically all his early 70's albums are great
Sly & The Family Stone - There's a Riot Goin' on and Fresh for sure
speaking of Otis Redding, I'm one of those outliers that thinks he made his best work just before he died - so his posthumous albums Love Man and The Immortal Otis Redding are both under-appreciated gems
sup homes - got an RYM account?
Gil Scott Heron. Here's his last album.
Also no one has said Curtis Mayfield for some reason. Basically his entire discography is awesome but I guess start with Roots
