The back pages of Incubus' catalogue add plenty of dimension to their alt-metal. They prove their hip-hop cred with the manic Big Pun cover "Still Not a Player," then get funky with some seriously killer licks on Prince's "Let's Go Crazy." While Brandon Boyd lets out his biggest screams on throbbing "Vitamin," he's just as convincing as a solo balladeer on "Runaway Train."
