I've been listening to Wilson Pickett, Sam Cooke, Ruth Brown, LaVerne Baker, Etta James, Aretha, Solomon Burke, Marvin Gaye, The Platters (who are arguably more Pop than Soul), The Four Tops, The Drifters ("On Broadway"---written by Barry Mann & Cynthia Weil---is as good as songwriting, singing, and production gets), The Shirelles, Stevie Wonder, Lloyd Price, The Temptations, Smokey Robinson & The Miracles, Hank Ballard & The Midnighters, Jackie Wilson (his "Baby Workout" is KILLER!), Percy Sledge, Clyde McPhatter (I bought his "Lover Please" when it was released on a 45 in 1962), James Carr (everyone has covered his "The Dark End Of The Street", including Ry Cooder), Otis Redding, Booker T & The MG's (one of my very favorite bands), Sam & Dave, Jr. Walker & The All-Stars, Martha & The Vandellas, Ruby & The Romantics (their "Our Day Will Come" is SO dreamy), and a few dozen others since the 60's. Oh yeah, and Ray Charles. Many, many white guys have spent their entire lives trying to sound as much like Ray as possible.
I've played the above music in numerous bands, but when the bassist of the somewhat-hippie-esque band I had just joined in 1971 looked through my record collection his response was "You like weird music". He didn't yet know that James Jamerson---a genius musician---played bass on many of them. I'll bet he does now.
