J.J. Cale (also JJ Cale), (December 5, 1938 - July 26, 2013), was a Grammy Award-winning American singer-songwriter and musician. Cale was one of the originators of the Tulsa Sound, a loose genre drawing on blues, rockabilly, country, and jazz influences. Cale's personal style has often been described as "laid back". Cale was also a very distinctive and idiosyncratic guitarist, incorporating both Travis-like fingerpicking and gentle, meandering electric solos. His recordings also reflect his stripped-down, laid-back ethos. His album versions are usually quite succinct and often recorded entirely by Cale alone, using drum machines for rhythm accompaniment.
