It's been over 40 years since Aerosmith dropped their self-titled debut album, and it still sounds remarkably fresh. It's all here: the power ballads, the killer guitar duo of Brad Whitford and Joe Perry and Steven Tyler's wild howl of a voice. The LP didn't find out a big audience outside of their native Boston, but it started selling really big three years later when Aerosmith blew up and "Dream On" came back out as a single. Tyler wrote the song years before he even joined Aerosmith and it remains their signature song, played at virtually every show the group has ever done. "Mama Kin" has also become a beloved classic. Aerosmith have cut better albums than their first one, but they never quite recaptured this youthful energy and loose vibe.
