Today would have been Robert Moog's birthday, and he is of course the inventor of the incredibly awesome-sounding Moog synthesizer that you'll hear everywhere in rock music.
My introduction to the Moog was in the early 90s, I picked up Gary Numan's brilliant album Telekon in a tiny record store in Maryland when I was a teen. I was hooked. I still listen to it.
My second big Moog exposure was on the album Return of the Rentals by the Rentals, the side project of former Weezer bass player Matt Sharp. ANOTHER great album.
One more album you might know Moog synths from is of course Abbey Road, one of the first to have Moog on it, specifically a bunch on "I Want You (She's So Heavy)" and even "Here Comes the Sun".
