Okay, okay so plenty of head shaking from the experts and the knowledgeable, but I just discovered Chuck Rainey. I'm learning Rock Steady by Aretha for an audition and have steadily fallen in love with the extraordinarily splendid bass line. So I do a little research and discover that I probably haven't just discovered him as he has played on so much. I have actually been listening to him for quite some time, notably with King Curtis. I just didn't know who he was.
The riff to the song is a joyous thing, rhythmically perfect, and perfectly repetitive with some little unexpected flashes. He then breaks into a few bars of pure inspiration before settling back onto the groove. Yum. It's beautiful.
A little more research and I find he played with Steely Dan who were of course one of Bruce Thomas favourite bands and Bruce has always been my biggest influence. So there we go.
Anyone familiar with Chuck's work who'd care to point me at other of his gems would render me eternally grateful.
