Henryhk,Even though you asked the question more than 2 years ago,since it is nevertheless out there,I was a rocknroll junkie.Did all the concerts possible,Led Z,Jethro T.,Grateful D,Steve M,Rod S,etcetera,etcetera.,.I went to more than I can remember.However all the time,even as a small child I loved 'jazz'.Back in the 'day' you could catch a glimpse of the hot artists on such shows as Ed Sullivan,Merv Griffin,Johnny Carson,Mike Douglas,etc.I loved them all,even as a 6,7,8 year old on up.What I would give now for copies of those times on dvd.Anyway,over the last 20 years or so r&r just began to fail doing anything for me.Now I have really re-discovered 'jazz' to the point that I am spending piles of cash stocking up on such as Oscar Peterson, Junior Mance,Ray Brown,Gene Harris,George Cables,and lots of younger 'bebop' artists.I can hardly seem to get enough of this 'stuff'.At 52,I guess I have become an old f--- or something.But my tastes in food and other things have taken sharp turns over the past several years also.I don't remember making decisions to make these changes,they just happened.Strange! Of course I still listen to my Herb Alpert and TJB collection.Can't part with that.
