Charles1dad, I work from home and have jazz in the background all day. I've listened to jazz all my adult life...a lot. I've heard a LOT of jazz. In the beginning my only exposure to jazz was jazz radio. If the DJ's didn't play it, I didn't hear it. No one played Thad Jones. My other exposure is from music recommended by friends. No one recommended Thad Jones. In the mean time I own over 4,000 albums (vinyl & cd combined), I listen to a paid subscription of Napster and Pandora. I have access to more music than I can ever listen to in a lifetime. There is SO MUCH great jazz out there and only so many hours in a day. There are still many great jazz artists's music that I've never heard. Thanks to Pandora, and the bottomless reservoir of jazz that's been recorded throughout history, I'll still be discovering new jazz recordings for the rest of my life.
