I still remember when I bought these CD's in the early 90's, when they were originally released. They were budget priced at around $10 or so. A friend of mine has a huge Jazz collection (lots of vinyl, but also CD's), several thousands of records, and he was buying many of these to fill holes in his collection. I was over at his place and we listened to some of them, and those which were well recorded and were interesting to me from a musical point of view, I then ordered those for myself. So, the 12 titles I ended up with weren't selected randomly, but carefully selected, and I think all of these titles are worth owning. I remember there were some titles which were not recorded so well, even though they would have interested me, and I didn't buy those then. I think there was a Dextor Gordon release, but probably recorded in the late 40's, so not on the same level as the mid to late 50's stuff.
