You had me at "Moog synthesizer," which will probably won't thrill @carolkean, but then, I've been seriously into them since Walter/Wendy Carlos and "Switched on Bach."
I wore the damned tape out. More than once. ;-)
And then there are so many other masters of the Moog, including Beaver & Krause (who helped introduce it to the musical world), undisputed keyboard master Keith Emerson, Stevie Wonder, Simon and Garfunkle (Bookends), and The Beatles (Abbey Road).
I heard one recently at Maureen's Jazz Cellar in Nyack NY, played by Neil Nail Alexander during a show of Peter Furlan's compositions. It took me waaaaay back! Such a distinctive sound! And @carolkean loved that I referenced the instrument - apparently her son is a big fan of Moog synthesizers, and she loves some music using them too.
