I grew up with my bro who is from the 50ies. If I hadn't listened to all his music, besides mine, I think my now 20 yr old son would have easily put me up to date with all the music I might have missed since Lady Day, Count Basie, Sinatra, Zappa, Hendrix, Manson, house music, you name it... I think he might even know all the stuff better than we do...
So yes....
