The MOVIE is CALLED: "TENACIOUS D"
The group with Jack Black, is 100% real pop/rock group called TENACIOUS D. This is what I found:
an American rock band duo composed of musician/actors Kyle Gass and Jack Black. Their music fuses vulgar absurdist comedy with rock music in a style that critics have described as "mock rock".
