Pretty much on the heels of the debut, the Airplane reconfigured itself and recorded what many call their masterpiece album. Not sure about that, but I will say it's a must-listen from a number of perspectives. It's not radically different than its predecessor and oddly enough, authentically feels like a bunch of hippies got together and randomly created a close-to-great pop record. Certainly, Grace Slick and her songs stand out the most, but just about every band member gets a big spotlight in this communal free-for-all. Balin's wonderful ballad "Today" and Jorma Kaukonen's meditative "Embryonic Journey" are my picks, while only the oddly conspiratorial "Plastic Fantastic Lover" left a bad taste in my mouth.
