15. Synthesizer Showdown (1985)
If there's one instrument that defined the sound of the 1980s, it was the synthesizer. It's impossible to imagine what the music of the decade would have sounded like had it not been invented. At the 1985 Grammys, Stevie Wonder, Howard Jones, Thomas Dolby and Herbie Hancock joined forces for the mightiest 1980s synth jam ever captured on film. It's a giant mashup of all their hits and needs to be seen to be believed.
