As the disco funk strains of ‘Butterfly’ burst into life, it's not hard to imagine jazz aficionados, who had already had a torrid time when Miles and Herbie blasphemously plugged in a few yeas before, grabbing a copy of Kind Of Blue and praying to it as if it were the bible itself. And yet that is entirely the wrong reference. The obvious formative elements of this sound, which Henderson both developed as a leader in his own right on previous albums such as Realization and as a member of Hancock's epochal Mwandishi ensemble, are Stevie Wonder, James Brown and MSFB, the majestic house band of Philly Int. So the real question is not so much whether the featured players, several of whom are also Herbie alumni, are up to it, chops wise, (which, they are incidentally), but rather, do the songs work as both radio and dance numbers? Do they groove? Do they make you want to sing? For the most part, yes. Bar a few numbers whose themes are on the syrupy saccharine side, the beat is hard enough — the B section of ‘Amoroso’ being a case in point — to fill any floors. There are moments when things sadly gloss out, but there's simply too much funk in the essential marrow of the music for it to be a dry as a bone affair.
