If you love long, wild and wierd guitar solos, supported by fantastic musicianship from the whole band, with a dose of humour, then this is the album for you.
I used to covet my friend's triple vinyl box set - and was so glad when it came out on CD. It's certainly not easy listening - a lot of this is quite extreme jazz-rock, strange time signatures, non-western scales and tunings, sudden stops and starts etc. If you play it at work, someone will probably ask you to turn it down. But that's the joy of it - this is heavy, strange stuff, to be played really loud, maybe while driving alone, slightly too fast, late at night.
My God - Zappa could play! And his band, in its various manifestations, was world-class.
