I've been listening for about 25 years since I was ~ 30. I've not seen many of the older legends but I did see Max Roach, Milt Jackson, Benny Carter and a number of others from the well known history of the music. I've been going to shows for many years but more heavily the last 7 years or so. I had a good run of seeing shows in the late 90's and early 00's as well. Although I've spent huge amounts of time listening to the history of this music - mostly post 1953 or so but that's my choice - but for the last number of years I'm mostly interested in the music of the past 40-50 years and especially the music of today / both the American and European based music - and mostly in the avant-garde free jazz areas.
