i'm still a big fan - of the music they created over 35 years ago. imo, most of these musicians (pop, rock, etc.) don't age very well. i have little or no interest in what the stones, mccartney, page, plant, and most of the other aging rockers are doing today. they had their time in the sun, and thanks to their recordings, i can still enjoy those days. i pray i never grow into one of those middle-aged farts you see in the audience at an oldies concert.
mind you, listening to older jazz musicians who still have their chops - now that's a whole different story!
