Greece’s Orthodox Church urged organisers of a Slipknot concert to cancel the band’s appearance at the Lykavitos theatre on Monday.
The band, who wear masks on stage, are well known for their extreme lyrics.
In its statement, the church said: “The members of the band have a shocking appearance, wearing black uniforms and masks that look like skulls.”
The nine members of Slipknot formed in 1995 in Des Moines, Iowa.
Slipknot Rules!
