There are many doors into the castle of showbiz - this is one of them:

A gun-toting musician forced a southern Brazilian radio station to play his debut album for more than an hour on Wednesday after apparently having no luck opening the doors of show business, the man's father said.

Marcus Vinicius dos Santos, 27, the vocalist for the rock group ACC — a Portuguese acronym for "Beyond the Gray Sky" — stormed disc jockey Marcio Paz's booth at Atlantida FM in the city of Porto Alegre and forced him to play his album "Phases of Life."

"He is a quiet boy," his father, Getulio dos Santos, told Reuters. "I'm surprised by what happened."

The five-member band portrays itself on its Web site as futuristic superheroes living in a post-apocalyptic world. Vinicius dos Santos goes by the name "Cram" and wears Alice Cooper-style black eye makeup.

The episode was reminiscent of the 1994 Hollywood movie "Airheads," in which dimwitted members of a rock band, fed up with rejection from music industry executives, take matters into their own hands and hijack a radio station to air their songs.

The Brazilian incident ended after about 70 minutes when Vinicius dos Santos surrendered to police, who had evacuated the building. Nobody was injured in the incident and Paz later informed listeners where they could buy the band's album.
