The best thing about record shopping for jazz albums is that you have plenty of elbow room; no one listens to it anymore. Well, old dudes and guys like Jimmy Mac do. So, every once in a while I find something that I shouldn't in there, some rare out-of-print limited edition original copy of something, but mostly I'm a listener- I'll leave the collecting to the nerds, I need these records to actually listen to.
You might find a Bobby Hutcherson record, or a record he played on every now and again. Buy it. Even this record, his under-rated debut solo outing. It features no numbers written by Hutch, but just take a look at that line-up! Andrew Hill (composed four of these pieces) on piano, Freddie Hubbard on trumpet, Sam Rivers on sax, Joe Chambers on drums and Richard Davis on bass.
I wish more people listened to jazz...
