Ramin Karimloo and Kerry Ellis have a tumultuous affair in the U.K. premiere of Murder Ballad, and their steamy duet, “Mouth Tattoo,” from the production has been released. Watch it above.

Murder Ballad—originally seen at Manhattan Theatre Club in 2013 before transferring to the Union Square Theatre—received its London premiere, officially opening October 5 at the Arts Theatre.

Ellis plays Sara, a young New Yorker who is torn between her dangerous ex-boyfriend (Karimloo) and her reliable husband (Norman Bowman).

Led by a sexy bartender (Victoria Hamilton-Barritt) who serves as the show's narrator, Murder Ballad documents the details of the torrid affair. When Sara breaks up with Tom, a gritty bartender, she runs into the arms of Michael, a quiet poetry student at NYU. But after the couple get married and have a daughter, Sara longs for her old, dangerous life and begins secretly seeing Tom at his bar downtown. As Sara’s passionate relationship with Tom intensifies, she begins to miss her old life with her husband and young child—but by then, it may be too late.

Conceived by Jonathan Larson Award winner Julia Jordan, with book and lyrics by Jordan and music and lyrics by indie rock singer/songwriter Juliana Nash, the London production is presented by Soundcheck Productions.
