Upon seeing him perform in a Memphis Club, he was asked by Delaney & Bonnie to join their band. Whitlock began a friendship with Eric Clapton when Delaney & Bonnie and Friends toured with him and would soon be part of Clapton's Derek and the Dominoes project. Co-writing many of the songs and playing and singing on most (that's him doing the lead vocal on his own "Thorn Tree in the Garden"), Layla & Other Assorted Love Songs was almost as much a Whitlock album as it was a Clapton album. With the same band, he played on George Harrison's All Things Must Pass and was also an uncredited musician on the Rolling Stones' influential Exile on Main Street a few years later.
The 1970s also saw him release four expressive solo albums. The first one, self titled, was released in 1972 and is the best of the bunch. Raw Velvet, while a little more uneven than the first, featured some of Duanne Allman's most heartbreaking and breathtaking slide playing (uncredited due to contractual legalities) on the track "Dearest I Wonder," recorded shortly before he died. After his 1976 album Rock Your Sox Off, Whitlock layed low for most of the '80s and '90s, living on a farm in Mississippi and doing some session work (though not even much of that). In 1999, he finally returned with the aptly titled It's About Time. ~ Rob Caldwell, Rovi
