I started collecting records from the early 50s to date. I have a lot of records.
I'll bet that I've played my promo copy of Brubeck's "Jazz Impressions of The U.S.A." several hundred times. It is one of my MONO demo records that I use, not only for my own enjoyment but to initiate the uninitiated on just how good MONO records sound. I found the promo version in a used record store back in the late 70s, It was still sealed. Paid six bucks for it, an astronomical amount at the time for a used record.
It still sounds great today. Paul Desmond was such a great alto player. That's music right there.
