The Simpsons' sixth season originally aired between September 4, 1994 and May 21, 1995. The first two episodes, "Bart of Darkness" and "Lisa's Rival", were held over from the previous season, as production was delayed because of the 1994 Northridge earthquake. The show runner for the sixth production season was David Mirkin. The sixth season won one Emmy Award, and received three additional nominations. "Lisa's Wedding" won the Emmy for "Outstanding Animated Program (For Programming One Hour or Less). Alf Clausen received a nomination in the category "Outstanding Individual Achievement in Music Composition for a Series (Dramatic Underscore)" for "Treehouse of Horror V", whilst he and John Swartzwelder were nominated for "Outstanding Individual Achievement in Music and Lyrics" for the Stonecutters' song "We Do" in the episode "Homer the Great". Finally, "Bart vs. Australia" was nominated for "Outstanding Individual Achievement in Sound Mixing for a Comedy Series or a Special". The Complete Sixth Season DVD was released in the United States on August 16, 2005, and September 24, 2005 in Australia. The packaging was changed from the standard box design used for the previous five seasons, to one shaped like Homer's head. After many fans complained of the change, a separate standard box was released.
