1. The Telephoned Vocal EQ (1979)
Producer Trevor Horn intentionally compressed his lead vocal with steep high-pass and low-pass band limiting (approx. 400Hz to 3kHz) to emulate an old 1950s crystal earphone. When played back on 1979 AM transistor radios, the track felt uniquely meta: a song about the obsolescence of radio sounding like the radio itself.
2. Downes' Polyphonic Architecture
Keyboardist Geoff Downes used early Roland and Solina polyphonic units alongside a Minimoog synth bass playing strict staccato eighth-notes. By moving between D♭, B♭m, G♭, and A♭, the harmony carried a melancholic nostalgia that bridged 1970s prog-rock virtuosity into new wave pop elegance.
3. The MTV Stereo Revolution (1981)
At 12:01 AM on August 1, 1981, MTV broadcast 'Video Killed the Radio Star' as its inaugural video. Cable television audio lines allowed full stereo bandwidth, wide chorus synthesizers, and punchy transients—rendering tiny mono AM speakers a relic of the past and sparking the music video era.
