Rockers Slayer are to be immortalised in their first English language biography. Author Joel MCIver promises to reveal plenty of Slayer secrets in his upcoming book on the heavy metal veterans. He says, "I've unearthed a ton of previously unheard stories from people close to the band and examined phenomena such as the enduring legend of (1986 album) Reign In Blood in enormous detail. You won't be disappointed." The only Slayer biography to date was published in Polish in December (06).
