Alton Ellis - Rocksteady

Here we've got some classic rocksteady by the father of rocksteady, a song, called, you guessed it, Rocksteady. Rocksteady is a musical form that originated in Jamaica that was somewhere between Ska and Reggae. Rocksteady has obvious ska influences, and the roots of reggae can really be seen in this type of music. This song was essential to the whole genre, blah blah blah. Can't for the life of me find any info about the album this is from. Goddamned shame if you ask me, seeing as he's such a revolutionary musical figure.
