Musician JJ Cale dies at 74

US singer-songwriter JJ Cale, who was behind chartbusters like "After Midnight" and "Cocaine", has died of heart attack at the age of 74.
An announcement on his personal website said he had passed away at a hospital in La Jolla, California, on July 26.
Born in Oklahoma, Cale helped to create a new music style Tulsa Sound, which combined blues, rockabilly, and country. He became famous in 1970, when Eric Clapton covered his song "After Midnight".
In 1977 Clapton also popularised Cale's "Cocaine". The two worked together on an album which won a Grammy award in 2008. As a performer, his biggest hit was "Crazy Mama", which peaked at No 22 on the US Billboard Hot 100.

Born in 1938, John Weldon Cale adopted the name JJ Cale to avoid being confused with John Cale of the Velvet Underground. Building up on the success of "After Midnight", he recorded Naturally - the first of his 14 studio albums.
He pioneered the use of drum machines, and was famous for his personal laid-back singing style.
However Cale always described himself as a songwriter rather than a singer, and his songs gained him a permanent place in popular music history, as he wrote a string of songs that were made more famous by artists including Clapton, Santana, Lynyrd Skynyrd and Tom Petty.
