That is one great run of luck! I'd have been all over the Bill Evans discs. Big, big fan here. I have pretty much all of the SACD reissues of his recordings. Just waiting for a reissue of some of his titles on 180g since earlier runs sold out. (Not the $100 MoFi UD1S though.)
Explorations is probably my favorite of the bunch you had pictured earlier. To me,
Waltz For Debby is not complete without
Sunday at the Village Vanguard, as they are both from the same set of gigs. I've overplayed both of them enough now that I'm taking a bit of a break from those two. Oscar Peterson is another I've enjoyed--his take on
West Side Story (on Verve) is likely my favorite of his.
The Kenton box you mentioned earlier...yeah, I could see not liking that one, if it's the Mosaic box I'm thinking of. I'm a Kenton fan myself (played in a big band for a few years myself), but that set is too "old" sounding for my taste. I like some of his later Capitol era stuff like Adventures in Time, Adventures in Jazz, Kenton in Hi-Fi, etc. His is more of the modern big band sound--very influential to those who followed him. Those Mosaic sets have fetched some good coin on the used market--jazz aficionados recognize that these are very well researched, thorough, high quality, and fairly priced when new ($10 per LP, $15 per CD originally). The tracks are presented in chronological order by recording date. I bought the 10-CD Maynard Ferguson
Complete Roulette Recordings set and never regretted it. (Now...Maynard Ferguson's
Hot! LP on Columbia? That one I regretted...and I bought it used for only a buck or two!
)
Amazing you could luck into that on your local Freecycle. Ours is terrible--it's mainly broken down old stuff, and more than half the posts are people asking for things. I saw one family pretty much beg for an entire houseful of appliances and furniture, one piece at a time, over several months. And I can't even say the local used record shops are all that good--most of what I've picked up has been too worn to be of any use to me, or scratched (the poorly lit stores are the worst). Just saying your haul was an incredible stroke of luck!
BTW, some of the guys I hang with online (elsewhere) meet up every year or two in Pittsburgh to hit the record shops. I'm tempted to join them one of these years.
