Currently listening to pop music of 1966. It all started when my live band, after last gig, discussed whose year of birth was the best popwise. One of us was from 1956, another from 1970 and I am from 1966. Not bad - the year of "Good vibrations", "Gimme some lovin'", "Strangers in the night", "These boots are made for walkin'", "Summer wine", "You keep me hangin' on", "Friday on my mind", "Under my thumb", "All tomorrow's parties", "Knock on wood", "Reach out I'll be there" and "They're coming to take me away, ha-haa". Frank Zappa made his first album. Walking in nextertown yesterday, I for the first time listened The Beatles' "Yellow submarine" from earplugs: I didn't know that song is panned in one ear, the instruments to another and sound effects are in the middle! By coincidence, few weeks ago mixing my band's forthcoming song I panned almost all instruments (including drums & bass) bouncing randomly.
This far the best (& only) synthpop I've found from 1966 is Perrey & Kingsley: eg.

Advices on 1966 synth music would be appreciated!
