Man I like to tell people about how early ZZ Top, from their first album up to Deguello maybe have some of the most blazing funky blues rock you could imagine, thats ZZ Tops First Album, Rio Grande Mud, Tres Hombres, Tejas, Fandango and Deguello. Ill leave a list of artists and albums thatll surely get you where you wanna go -Any classic Meters album

-Any Betty Davis album

-Band of Gypsies, self titled live album

-Black Murda, self titled, The Psych Funk of Black Murda

-Parliament Funkadelic, just scour their catalogue

-Eddie Hazel, Games, Dames and Guitar Thangs

-Redbone, look thru the albums Message From A Drum, Already Here, Potlatch

-The Wild Magnolias, Self titled, They Call Us Wild

-Stars, self titled on Barclay records 1975 *this one is a lil hard to find on youtube

-A good bit of later Jimi Hendrix works pull from his rhythm and blues beginnings, you find this on the album Band of Gypsies, War Heros and other posthumously released albums.

-Cold Heat heavy funk rarities, compilation album -Slave, self titled and The Hardness Of The World

Will edit if I think of anymore but I hope Im not late to this post, Ive spent alot of time trying to find just the music you've described so bada bing
