As one of the breakthrough artists at the 2001 Ozzfest, Papa Roach [ tickets ] was armed with insults, manic behavior, angst-ridden lyrics and lead singer Coby Dick's omnipresent bloody forehead.

Papa Roach let that anger fester for two albums. But something happened on the way to its third release, "Getting Away With Murder."

The band grew up.

Dick strong-armed his addictions and retreated to the use of his real name, Jacoby Shaddix. His lyrics became more positive and socially conscious. Not only is this maturity apparent on disc, but on stage.

Once known for beating his head with a microphone until it bled, Shaddix now draws attention to himself on stage for other reasons. During a tour stop Tuesday (4/19) at the Marquee Theatre in Tempe, AZ, Shaddix traded his self-abusive behavior for frequent wide grins and a gripping stage presence.

Lost in a sea of strobe lights in the opening minutes of the show, Shaddix stood on top of a monitor and pumped his fist, creating a striking scene for the near sold-out crowd. As the lights were tamed, Shaddix's trademark scowl gave way to smiles and a slew of jokes. He hinted to his past behavior, but just when he was about to make a derogatory comment about the audience, he changed his mind. "No, that's disrespectful."

"Are you ready to rock? I want to see this f---ing pit explode," he added, leading into the apropos "M-80 (Explosive Energy Movement)."

Shaddix's vocals were dead on for most of the 90-minute show, as were those of supporting vocalist/guitarist Jerry Horton. The band's newfound energy was apparent, as well. Horton and bassist Tobin Esperance thrashed around the stage with their instruments, serving up an arena-ready performance to the club patrons.

The band's love of its new material was evident throughout the show. Horton's searing guitar in the song "Getting Away With Murder" was powerful and drummer Dave Buckner's beats were spine rattling.

Introducing "Harder Than a Coffin Nail," Shaddix revealed old wounds: "This is a song about addiction. I got to wake up to that s--- every day. This music saved my life right here." He revisited the dark times before the hit "Scars": "This is about one of the darkest moments in my f---ing life. One f---in' day I didn't want to wake up."

The crowd couldn't have been a bigger support group for the recovering Shaddix. They fashioned hearts out of their hands and sang along feverishly--just had they had done throughout the show.
