Break Up is a collaborative album between Pete Yorn and Scarlett Johansson. The first single, "Relator" was released as a digital download on 25 May 2009. The full album was released by Atco/Rhino on 15 September 2009. Pete's brother Rick Yorn is Scarlett's manager.
Johansson spoke about the project at the time of the "Relator" single release; "The idea of two people vocalizing their relationship through duets...I always thought of it as just a small project between friends. It perfectly captured where I was in my life at the time".
During 2009, Yorn stated that he would like to do some live shows with Johansson to promote the album. By September 10 that year, Johansson and Yorn performed "Relator" on the French television show Le Grand Journal. It was Johansson's first live performance on television.
The duo were then interviewed by KCRW on October 7; they talked about past, present and future projects, and performed the single "Relator" along with "Blackie's Dead", "Search Your Heart", "Shampoo" and a cover of The Kinks' "Stop Your Sobbing". They also stated that they would like to tour, but because the short time the songs give them to perform (around 29 minutes), they would like to turn the concert into a dinner if there's the demand for them to tour.
CD 2 includes live versions recorded at The Village Recorder in Los Angeles on October 7, 2009. Originally broadcast on KCRW's Morning Becomes Eclectic with Jason Bentley. This CD was launched like the "Live At KCRW.Com EP" on Amazon.com, and after included in "Break Up (Deluxe Edition)".
