The family of slain guitarist 'DIMEBAG' Darrell Abbott have blasted a forthcoming biography of the music star. The ex-PANTERA rocker was shot dead when an obsessed fan went crazy at the Alrosa Villa nightclub in Columbus, Ohio during a Damageplan show in December 2004. Music journalist Zac Crain's forthcoming biography Black Tooth Grin: The High Life, Good Times, and Tragic End of 'Dimebag' Darrell Abbott chronicles the guitarist's rise with Pantera. However, Abbott's family claim they have "not authorised nor cooperated with Crain", reports In a statement, they add, "Mr. Crain did not know Dimebag personally. Mr. Crain's request to the family was denied. Among other reasons, during his tenure as music editor of the Dallas Observer, Mr. Crain wrote nothing but negative reviews about Pantera's music."
