I too was wearing my Moog t-shirt yesterday. By chance I should add.
The man was a genius. Music is better for his efforts, and the world more sad for his passing. I had been following his progress and was hoping for better news than this...
I still own, and use, my beloved MiniMoog, Moog Source and Moog Taurus II. I've had them for 20 years or thereabouts and I'm not planning on stopping using them any time soon. I wonder how many synths we'll be saying that about in 20 years time that come from the modern crop?
Dr. Robert Moog - RIP sir.
