Al Kooper

Al Kooper is an American songwriter, record producer, and musician. Throughout much of the 1960s and 1970s he was a prolific studio musician, including playing organ on the Bob Dylan song “Like a Rolling Stone”, French horn and piano on the Rolling Stones song “You Can’t Always Get What You Want”, and lead guitar on Rita Coolidge’s “The Lady’s Not for Sale”. He also formed and named Blood, Sweat & Tears, though he did not stay with the group long enough to share in its subsequent popularity. Kooper produced a number of one-off collaboration albums, such as the Super Session album that saw him work separately with guitarists Mike Bloomfield and Stephen Stills.
