One of my favorite musicians of all-time is Billy Preston. The essential studio man, he played organ, electic piano, and clavinet on a number of great albums including Bob Dylan’s Blood on the Tracks, The Rolling Stones Exile on Main Street, and The Beatles Let it Be. In fact, he was the only non-Beatle to ever receive song-writing credit for his piano contributions on Get Back.
So if ya don’t know the radical music of Billy Preston, consider yourself warned. The man can lay down some funk. I recommend starting with Billy Preston, Wildest Organ in Town!
