Benny Goodman is another story. Maybe it's because of the generally inferior sound quality of most Big Band recordings which inhibits my appreciation to the point where I avoid buying Big Band music altogether.
I have some good news to report. Our local small town independent record store has acquired an extensive vinyl collection (50,000+ records) so I'll have a handy source to peruse for years to come all within easy walking distance. Who knows what lost gems are contained within a collection that large?
