John Weldon "J. J." Cale was an American singer-songwriter, recording artist and guitarist. Though he deliberately avoided the limelight his influence as a musical artist has been widely acknowledged by figures such as Mark Knopfler, Neil Young and Eric Clapton, who described him as "one of the most important artists in the history of rock". He is considered to be one of the originators of the Tulsa Sound, a loose genre drawing on blues, rockabilly, country, and jazz. Many songs written by Cale have been recorded by other artists, including "After Midnight" and "Cocaine" by Eric Clapton; "Call Me the Breeze" by Lynyrd Skynyrd, John Mayer, Johnny Cash and Bobby Bare; "Clyde" by Waylon Jennings and Dr. Hook; "I Got The Same Old Blues" by Captain Beefheart, Lynyrd Skynyrd and Freddie King; and "Magnolia" by Beck, Lucinda Williams, Iron and Wine, Jose Feliciano and Ben Bridwell. In 2008 he, along with Clapton, received a Grammy Award for their album, The Road to Escondido.
