After weeks of speculation about who will be sharing the Ozzfest stage this summer with Black Sabbath, Iron Maiden, Shadows Fall and Zakk Wylde's Black Label Society, the big secret's finally out: Heavy metal quartet Mudvayne have been named the final mainstage act.

A photo of the band was posted Monday morning (April 4) on the Ozzfest 2005 Web site, replacing the ominous band silhouette and large white question mark that appeared in that mystery spot ever since the roster was announced just a few weeks ago (see [article id="1498146"]"Ozzfest Lineup, Itinerary Announced"[/article]).

There had been much speculation since the initial Ozzfest 2005 announcement concerning who the surprise headliner might be. Anthrax, Disturbed, Slayer, the surviving members of Alice in Chains (with Zakk Wylde handling vocals), System of a Down, Megadeth, Rammstein, Velvet Revolver and Damageplan (with Wylde on guitar, filling in for the late "Dimebag" Darrell Abbott), were all rumored to be that band.

Mudvayne, whose new album, Lost and Found, hits stores April 12 (see [article id="1497672"]"Mudvayne Lose The Makeup, Find Inspiration In Isolation"[/article]), are currently on tour with Life of Agony and Bloodsimple. A spokesperson for the band could not be reached for comment.

Ozzfest, which also features Killswitch Engage, the Black Dahlia Murder, Rob Zombie, As I Lay Dying, Mastodon, the Haunted, In Flames, Arch Enemy, Soilwork and Trivium, kicks off July 15 at Mansfield, Massachusetts' Tweeter Center, and wraps up September 4 in West Palm Beach, Florida, at the Sound Advice Amphitheatre.
