Big Mess is the second solo studio album by American singer, musician, and composer Danny Elfman. It was released by Anti- and Epitaph Records on June 11, 2021. The album is Elfman's first studio album outside of his film and classical compositions since the 1994 album Boingo with his former band Oingo Boingo, and his first solo pop release since the 1984 album So-Lo. Although Big Mess features former members of Oingo Boingo, such as Steve Bartek, Warren Fitzgerald, and Marc Mann, it is not an Oingo Boingo collaboration in the vein of So-Lo.
