AC/DC, Metallica, and Sabbath/Ozzy are still cutting albums, too. I find it refreshing when I overhear at work a young person talking away excitedly to another young person about this "new song" they heard, from a band older than they are. The old stuff is still good stuff!
Ozzy was the first show I ever saw (with Korn, and Deftones - Ames Iowa)
