Bob Mould (b. 16 October 1960, Malone, New York) is an American musician, who attended Macalester College, and is principally known for his work as guitarist, vocalist and songwriter for influential 1980s punk rock band Husker Du. After Husker Du split at the end of the decade, Mould formed Sugar, in the early 1990s. He released two solo albums between Husker Du and Sugar, Workbook and Black Sheets of Rain.

During the recording of his album The Last Dog And Pony Show, Mould recorded an experimental dance music-influenced instrumental, that eventually led to his forming a new side project, LoudBomb, a pseudonymn deriving from an anagram of his name.. He has released at least one CD so far under this name.

Mould took a brief break from the music world to get involved with another passion of his, professional wrestling, when he joined WCW as a scriptwriter for a brief period. Creative differences with some of the other writers of the league led to Mould leaving the company and returning to music. When he released the album Modulate in 2002, he thanked some of the wrestlers he associated with, most notably Kevin Nash and Kevin Sullivan, in the album's liner notes.

In addition to his solo work, Bob Mould is also a live DJ in collaboration with DC-area dance music artist Rich Morel, under the collective banner Blowoff. A recording under that banner is said to be in the works. Both LoudBomb and Blowoff have led to Mould being asked to do remixes for a variety of dance and alternative rock artists. A recent remix of the Interpol (band) song "Length Of Love" has led to more critical acclaim for the veteran artist.

Although he has been giving solo semi-acoustic performances (halfway through the set, he will switch to electric guitar) since his departure from WCW and prior to the release of Modulate, the impending release in 2005 of his solo album Body Of Song was cross-announced with his first band tour since 1998. Brendan Canty, best known as the drummer for Fugazi, and Mould's Blowoff collaborator Rich Morel, had been tapped at the time of this writing, to play drums and keyboards, respectively, for the tour, scheduled to start in the fall of 2005.
