While Hendrix remains most famous for his hard rock and psychedelic innovations, more than a third of his recordings were blues-oriented. This CD contains 11 blues originals and covers, eight of which were previously unreleased. Recorded between 1966 and 1970, they feature the master guitarist stretching the boundaries of electric blues in both live and studio settings. Besides several Hendrix blues-based originals, it includes covers of Albert King and Muddy Waters classics, as well as a 1967 acoustic version of his composition "Hear My Train A-Comin'."
