Aware of the singles and the grooving Grapevine, my first impression is utter amazement at the brilliance of the opening song until it lingers just a little too long on one musical phrase before returning to the rocking first part again. Just awesome. I think Cosmo's shows distills the essence of CCR better than any of their preceding bluesy albums with elements of all their styles (rock n roll, blues, soul, country, "swamp" and psychedelic). I'll have to listen to their earlier albums again now, but I think this is my favourite CCR. Essential.
