Slothrust (pronounced sloth-rust, IPA: ['slɔθ.rʌst])  is an American alternative rock band from Boston, Massachusetts, formed in 2010. Slothrust consists of Leah Wellbaum (vocals, guitar) and Will Gorin (drums). Wellbaum and Gorin first began collaborating as students at Sarah Lawrence College. After performing in various school groups, the two joined to create music with a "heavier" sound.  The name Slothrust came together as a combination of Wellbaum's former project "Slothbox" and "rust" to signify time passing.
