That’s the spoiler recap of Herbie Hancock’s performance at the 26th Annual Grammy Awards, in 1984. He was there to play his crossover hit “Rockit,” an early hip-hop touchstone, ubiquitous in the clubs and on the street. (It won for Best R&B; Instrumental that year.) What nobody could have foreseen was that his performance would be a Grammy Moment, to use the Recording Academy parlance, of rare cultural impact — one of the most stealthily influential in the history of the awards.
