Sleigh Bells continue their 21st Century domination with the duo’s third record in three years, Bitter Rivals. On the album’s just-released title track, vocalist Alexis Krauss sounds sassy and caustic as ever, but also embraces more of a pop influence; “Bitter Rivals” only adds more fuel to the Sleigh Bells popularity fire. How long until we hear these guys on the radio? The new album drops October 8 via Mom + Pop.
