My father is really into blues music. He has had a cd by JJ Cale called naturally for as long as I can remember. The cover have always appealed to me and I think that it is one of the best album covers I know. Recently, thanks to Spotify, I´ve started to listen through Cales long list of songs. It´s a mixture of blues, rockabilly, country, and jazz. Here is the super brilliant album art !
