30 Seconds to Mars "sacrifice tofu" before their shows.

The rockers insist their vegan diets don't lend themselves too well to a rock 'n' roll lifestyle, so they often have to improvise when performing pre-performance rituals.

Frontman Jared Leto joked: "Well there was a time when we used to sacrifice goats but then we all became vegans so we've been sacrificing tofu before the shows!"

The group - also consisting of Jared's brother, drummer Shannon Leto, and guitarist Tomislav Milicevic - also claimed to enjoy relaxing mud baths before they go on stage.

Jared added in an interview with MySpace music: "Shannon introduced us to the pleasures of a mud bath. He carries the mud with him from a very special site in Mexico, which is heavy."

Jared also said the group felt they had reached a "milestone" when they played London's Wembley Arena recently.

He added: "We played Wembley - insane. Kind of a milestone. Even in the States you hear about Wembley Arena, as a kid you heard about that for years.pretty great to play there."
