This album, and I'd say Herbie Hancock in general, is one of the few that's mastered the art of being really really cool. The music here resonates with the listener not on a spiritual, emotional, or even visceral level - but on a level that's very subdued, not in plain sight but still strongly present...a "bass" level. Each percussive element, drum fill, key hit, bassline, and sax note is sequenced meticulously to ensure that these relentless grooves can go, at times, completely off the rails. This aspect can lead to something undeniably tight and groovy like on the faster vicious saxophone and key solo passages of 'Sly'. Or it can lead to something satisfying like that cute refrain on 'Watermelon Man' that uses space effectively enough to keep the listener slightly disoriented, constantly guessing, but hooked all the same. That key hit acting as an almost starters-pistol for this one particular passage is great... In general, I'd say 'Watermelon Man' is my favorite track here - it's just such an iconic piece of jazz, especially given its bottle flute opening. 'Chameleon' is another song that's just cool - an iconic and funky bassline is at the core of this one, and while it stays in that very repetitive place for a good chunk of the song, it eventually evolves into something unrecognizable with those keys and synth, becoming warmer and more elegant as the track blooms and opens up. Elegance is also the name of the game on the closer 'Vein Melter', especially in those closing minutes. It's easily the least "aggressive" song here and serves to send off an otherwise explosive album. Very few albums land in this unique space between electronic, jazz, and funk music. Because of that, I'd argue that this album lacks a strong "musical" identity, at least in the traditional sense...that's to say it's very eclectic in its styles and transitions. But there's a kick here, one you get from very few albums, a sense of satisfaction that's difficult to pin down, but is made clear as day when actually listening.
