Metal Circus is an EP by Hüsker Dü, released in 1983. As one of their early records, it was largely rooted in the band's initial hardcore punk style. However, signs of a new, poppier influence emerge on Metal Circus, particularly in the songs sung by Grant Hart ("It's Not Funny Anymore" and "Diane"). It also features some of Bob Mould's most passionate singing and shows further development in his guitar playing. Harmonic, chorus-type effects applied to Mould's guitar are more prominent.
