Sleigh Bells is an American noise pop musical duo based in Brooklyn, New York, formed in 2008. The duo consists of vocalist Alexis Krauss and guitarist Derek Edward Miller. After signing to N.E.E.T. Recordings and Mom+Pop, Sleigh Bells released their debut album, Treats, on May 11, 2010. Their follow-up album, Reign of Terror, was released on February 21, 2012. On October 8, 2013, the band released their third album, Bitter Rivals. Both members of Sleigh Bells had previous experience performing and touring in a musical ensemble. From age seventeen to twenty-two, Florida native Derek Miller was a guitarist in the hardcore band Poison the Well. He last performed on the band's 2003 major-label debut You Come Before You, leaving the following year due to creative differences. He wrote songs while working as a waiter or barback in various cities across the United States. Alexis Krauss grew up in New Jersey and has a background in theater and television. As a young girl she appeared in a Nickelodeon Magazine commercial.From age twelve to sixteen, Krauss performed in the teen pop group RubyBlue. After RubyBlue broke up, Krauss went to college (majoring in political science), taught Spanish to elementary school children in The Bronx and performed at weddings on the side for fun. In March 2008, Miller moved to Brooklyn to find a female vocalist for some song demos he was working on. In April 2008 he started working at Miss Favela—a Brazilian bistro in Williamsburg, Brooklyn—and in July 2008, Krauss and her mother dined at the restaurant. Miller expressed his interest in finding a female vocalist for his new project and Krauss was immediately volunteered by her mother. The two met in a park and listened to Miller's demos through headphones. In a 2012 interview, Krauss remembered her first impressions, saying: "Derek's music sounded like a really interesting challenge, but I wasn't thinking he was somebody I wanted to develop a creative relationship with." Krauss was pursuing a Rhodes Scholarship at the time, but decided to join forces with Miller instead.
