While John Cale is one of the most famous and influential musicians ever, it's almost impossible to define his style. In Cale's music there's always a tension between the experimental and the accessible.
Mid 60's, together with Lou Reed and Sterling Morrisson, he formed the Velvet Underground. After leaving the band in 1968 he went solo. Since then he released over 30 albums. His last album HoboSapiens shows Cale at his most elegant, energetic and innovative.
