The Tenacious D rock band with Jack Black and Kyle Gass are back with a new album, “Rize of The Fenix,” coming out on May 15, 2012. (Yes, folks, that’s a penis with wings on the cover art.) This “mock rock” band is not for the faint of heart as their music puts the vulgar into vulgarity. If you’re a writer, you can appreciate the colorful usage of language sung to hilarious melody. Jack Black is far more funnier in Tenacious D than he was in his last movie, “Your Highness.”
