Ray Barretto : Acid

Ray Barretto was a Grammy Award-winning Puerto Rican latin musician, widely credited as the godfather of Latin jazz.
By the time 1968 rolled around, Ray Barretto was a celebrated studio session player whose hard-driving conga rhythms could be heard all over the records of Dizzy Gillespie, Cal Tjader, Cannonball Adderley, and countless others. Once he dropped Acid onto the music world, Barretto firmly established a reputation for himself as an innovator in his own right.
Like the drug itself, Acid had a mind-expanding influence on everyone, allowing for a far more adventurous and eclectic edge to slip into New York's Latin music scene. A lot less psychedelic than its title and cover might lead you to believe, Acid remains one of the most far-out fusions of Latin and soul music ever conceived.
Catchy as hell, the records four original Latin/soul numbers ("Mercy, Mercy Baby", "The Soul Drummers", "A Deeper Shade of Soul" and "Teacher of Love") are obscure classics loaded with plenty of vintage '60s soul references—punchy James Brown and Stax Records sounding horns, thickly grooving bass lines, fat-back drums, and soul catch-phrases such as "What I say," "Lord have mercy," "Come on, come on baby" and "Sock it to me!"
