Smash Mouth

The Ally Challenge presented by McLaren is turning up the volume with a Friday night headline act that'll have you on your feet.

From grunge to nu-metal, pop-punk to Brit-rock and all the alternative stuff around it, the '90s were a great period for rock music.

See what they said.

Smash Mouth's founding frontman Steve Harwell, 56, passed away after health struggles. His legacy includes hits such as "All-Star" and "Walkin' on the Sun" and iconic placement in the "Shrek" soundtrack.

Steve Harwell—founding member and original frontman for Smash Mouth—has reportedly entered hospice at his home with "only days to live."

Better luck next year.

These songs rocked, then rolled over into the mainstream.

Fiercely faithful or creatively original, these covers caught our ears.

Did you have a clue that the dinosaur was actually Jericho?

Smash Mouth, Trapt, Fozzy and other acts played the mass gathering.

And guess how many wore masks?

Lit, Drowning Pool, Night Ranger, Adelita's Way and more are playing too.
