The group which created Layla

The group which created Layla and Other Assorted Love Songs grew out of Clapton's frustration with the hype associated with the supergroups Cream, and the short-lived Blind Faith. After their dissolution, he joined Delaney and Bonnie and Friends, whom he had come to know while they were the opening act for Blind Faith, for a British tour.

After that band also split up, a Delaney and Bonnie alumnus, Bobby Whitlock, joined up with Clapton; the two spent some months writing a number of songs "just to have something to play", as Whitlock put it. These songs would later make up the bulk of the material on Layla and Other Assorted Love Songs.

After a tour with Joe Cocker, some more of the personnel from Delaney and Bonnie joined up with Clapton; he attempted to avoid the limelight in a group dubbed Derek and the Dominos, and booked a British tour of small clubs. The group's name had reportedly resulted from a gaffe made by the announcer at their first concert, who mispronounced the band's provisional name – "Eric & The Dynamos" – as "Derek & The Dominos". In fact, Eric chose the name "Derek and the Dominos" because he did not want his name and celebrity to get in the way of maintaining a "band" context.

After the tour, they headed for Criteria Studios in Miami to record an album.

The other source for Layla was Clapton's personal life: he had fallen in love with Patti Boyd, the wife of his friend George Harrison. Not even heroin, which Clapton had then begun to use, could dull the pain. Dave Marsh, in The Rolling Stone Illustrated History of Rock and Roll, wrote that "there are few moments in the repertoire of recorded rock where a singer or writer has reached so deeply into himself that the effect of hearing them is akin to witnessing a murder, or a suicide... to me, 'Layla' is the greatest of them."

Love Songs

Layla and Other Assorted Love Songs is a blues-rock album by Derek and the Dominos. It is now consistently regarded as one of the greatest rock and roll albums of all time, and one of the high points in Eric Clapton's career.

It was released in December of 1970; critical reception at the time was mixed, and it had mixed sales success. It peaked at #16 on Billboard's Pop Albums chart but, remarkably, in Britain it never made the charts at all.

In 2003 the TV network VH1 named Layla and Other Assorted Love Songs the 89th greatest album of all time. In 2003, the album was ranked number 115 on Rolling Stone magazine's list of the 500 greatest albums of all time.
