re: "Two career" bands/artists

I feel like I should mention Iron Maiden. After a pretty long & successful run, Bruce Dickinson & Adrian Smith left, and for several years they slowly started circling the drain after a couple of mediocre albums with Blaze Bayley. Right when it seemed like it was time to call it a day, Dickinson & Smith came back. Not content with just living off their past, they've since released five studio albums (including a double, clocking in at 90+ minutes), and have done well on the concert trail too...
