This is one of my most played albums ever, and easily my favourite Jefferson Starship album. This was the point where the floating pool of musicians from the Grace Slick/Paul Kantner solo albums (after Jefferson Airplane's demise) coalesce into a regular band, and Marty Balin (Jefferson Airplane's other great singer) returned. But it still has some of the feel of the transitional period between JA & JS (this was preceded by 'Blows Against the Empire', 'Sunfighter', and 'Baron von Tollbooth and the Chrome Nun') - they became much more commercially orientated after their next album 'Red Octopus', featuring the big hit 'Miracles' that rocketed them into stadium rock superstardom, and though still great for another 2 or 3 albums they were beginning to lose the charm that had kept Jefferson Airplane fans with them. If you like anything from the Airplane/Starship crowd between "...Takes off" and "Earth" then you need this. 5 of the 8 tracks are indispensable - the others are ok too. Grace's contributions "Devil's Den" and "Hyperdrive" are among her best (though her contributions almost always were). The rhythm, the bass and Papa John Creach's fiddle on "Devil's Den" are also stunning. "Hyperdrive "is a long epic with some lovely tasteful guitar arpeggios from Chaquiqo and Grace giving a performance that puts her up with Aretha Franklin or anyone. Imagine Pink Floyd meets Aretha Franklin of a long science-fiction ballad. You couldn't get this from anyone else. And Marty Balin's "Caroline" is possibly his best song ever, again given an epic treatment. Achingly romantic and then it rocks! Paul's "Dance with the Dragon" is a great rocker that they continued to play live for many years, and "All fly away" is a lovely floaty science-fiction song with beautiful harmonies reminiscent of their approach on "Spitfire" years later. Tears! Speechless! Buy it!
