(CNN) -- Brooklyn noise-pop duo Derek Miller and Alexis Krauss, aka Sleigh Bells, may have just released "Reign of Terror," the follow-up to their critically acclaimed debut, "Treats," but, believe it or not, they have only written one song together so far. "Comeback Kid," the lead single and last song that made it to "Reign of Terror," was their first collaborative effort. As Sleigh Bells' story of origin goes: Miller, a former guitarist for the Florida hardcore band Poison the Well, was writing what would become "Treats" while waiting tables in New York. He served Alexis Krauss, a former teen-pop singer, and her mother. Miller mentioned he was looking for a singer for his unfinished demos and Krauss' mom stepped in to broker the deal.
