The first album of the first super band in history, is one of the best debuts ever recorded. Although the best of the band was yet to come, we must not fail to recognize that for this reason it does not lose any of the attributes as a masterpiece, despite having only half of the songs as own compositions and the rest by versions, in the you can already see the powerful conjunction between blues and rock, with psychedelic influences as in "I Fell Free" or "N.S.U".
