Smash Mouth

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."

These songs rocked, then rolled over into the mainstream.

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

Remembering the 1999 hit this Earth Day.

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

But aren't they the same person?

Imagine there's no 'All Star.'
