What NKOTB were to the '80s, the Backstreet Boys were to the '90s: worshipped by tweens, hated by rockers and eventually relegated to the "what was that one song?" dustbin before the millennium flipped. But to paraphrase one of their biggest hits, they don't want it that way. By teaming up with their forebears for an album and tour, BSB achieve two things: They contextualize themselves in a musical landscape in which they have legitimate claim to being pioneers, and they look young by comparison. Win-win.
