of the Sons and Jeremy Larson, all of whom have worked on the upcoming album. The EP was also released on limited edition vinyl on March 24, 2009. The group went to work writing and recording their second full-length record in their home studio in New Orleans. The album, Armistice, was released in the United States on Teleprompt Records/Warner Bros. Records on August 18, 2009. During the recording of the album, short videos were posted to the band's YouTube profile. These videos documented the work going on in the studio, including street interviews where New Orleans locals were shown samples of the album (which couldn't be heard in the video), recording their reactions. Any clips of actual music from the new album was presented in such a way that it only hinted at what the album would eventually sound like. On April 4, 2008, Goodwin Films announced they were working on a documentary film about the making of Mutemath's new record. According to the biography, the group had almost called it quits during the writing of the album. The band had written about 16 songs in the three years spent on the road touring and had expected to cut the list to 10 after settling down to record in their New Orleans home studio. Weeks of working with old ideas and bickering between the bandmates led the group to begin searching for an outside producer to help focus the group and stabilize the tension. During this search, the group met producer Dennis Herring and after hearing his input, decided to scrap all the previously written material and start from scratch, bringing Herring on board as producer of the album. The band worked over the next three months writing almost 20 new songs that would shape Armistice. The band then spent time at Herring's studio in Oxford, Mississippi, recording the final touches of the album. On January 14, 2009, King said in an interview that after a break for the holidays, they would "get back to recording in hopes of having everything done in March so that the album can come out in August. It has taken way longer than we would have ever imagined but we're just not done with it yet." Additionally, he mentioned that the album was Mutemath's first album which involved collaboration among all four members of the band. The title for the sophomore record was confirmed
