It's hard to conceive a better musical foil for Steven Tyler than his longtime partner and occasional adversary. For more than 40 years, Joe Perry's monstrous, blues-on-steroids riffs have been Aerosmith's bedrock. And his solos, jutting out from "Walk This Way" or slashing boldly through the high-gloss production of later hits like "Janie's Got a Gun" and "Cryin'," have a caffeinated energy that's every bit Tyler's match.
