Can you recognize this rock star from his yearbook photo? Here's a hint: He's the guitarist in one of the most popular and enduring bands of the '90s, who have done more than any of their peers to connect with previous generations of classic rockers.

He's a well-known, proud member of the Kiss army, even reportedly admitting to "stealing" one of Ace Frehley's guitar solos, and his group has performed live with or covered songs by a vast array of rock legends, even collaborating with one on a full-length record.
