This seminal fusion classic, is a mindblowing album, musically, and technically. Herbie's band on this album includes Bennie Maupin, on reeds, Paul Jackson on bass, Harvey Mason, drums,and Bill Summers on percussion. They really tear it up, from start to finish. The classic, "Chameleon", features a memorable solo, by Herbie on the ARP soloist synth, which is a very free, frantic, yet masterfully played. This only primes you up, for his very melodic Fender Rhodes solo, later in the tune, which is accentuated by his overdubbed ARP synth strings, which given the time period sound very realistic. After that very pumping tune, the rush doesn't stop there. The band then performs Herbie's classic "Watermelon Man" given a fantastic, new treatment with an African influenced intro, by Summers blowing in Beer bottles. After the intro, it then goes into the familiar bassline, to a funky R&B grinding groove, that even younger teenagers may appreciate. "Sly", dedicated to Sly Stone, the great soul singer, is a tune, that transforms into a heavy doubletime Latin groove, with Bennie, taking a furious turn on Soprano sax, followed by a equally ferocious Hancock Rhodes solo. Finally, "Vein Melter", is an almost disturbingly relaxing groove, that in a way can, be said to be a precursor to ambient electronic type music. With a hauntingly slow march beat, set up by Mason, with very liquid solos by Bennie, and Herbie. Technically, the album is amazing. Since it is mostly multitracked, it is so slickly produced, that each track actually sounds as if it was just one performance. Even though 5 men are on the album, it really sounds like so much more. This is a great album, and even for a more acoustically oriented Hancock fan, such as myself, it is really pleasing to hear Herbie strictly electric.(although I really admire Herbie's Rhodes playing) Remastered in 20-bit sound, it sounds really very recent. I really suggest this one, highly!! "Headhunters" has been one of the most exciting listening experiences I have had in quite a while.
