If you’ve ever wondered what Mick Jagger and Jimi Hendrix might have sounded like together, this southern soul gem is for you. "Mercy, Mercy", off of See-Saw, Don Covay’s 1966 LP reportedly has the young Mr. Hendrix playing session man (though Covay was reportedly no slouch himself). What sticks out even more though is Covay’s tenacious shout-speak bluesy wail, which played a large influence on Mick Jagger’s vocal style. The song itself is a funky-blues gumbo, something you’d expect to hear come out of roadside bars in the Louisiana night. Both Wilson Pickett and The Rolling Stones would later cover it, but the original is a definitive lost classic.
