There’s an emblematic photograph of Herbie Hancock on the back cover of his album Sunlight, which he began recording 40 years ago this month. He’s depicted against a red backdrop with a Sennheiser vocoder headset on his cranium, which is bowed in deep focus.
He’s also totally boxed in by his keyboards. The LP insert sleeve includes a diagram to help identify them by name: Oberheim Polyphonic Synthesizer, Sequential Circuits Prophet Synthesizer, ARP 2600, ARP Odyssey, Micro-Moog, Mini-Moog, Poly-Moog. (This is not a complete tally.)
