Ugly Side: An Acoustic Evening With Blue October is a liveacoustic album by Blue October. It is their third live album, and eighth album overall. The album was recorded during a sold out three-day tour of Houston, Austin, and Dallas July 22–25, 2010 during which the band played two acoustic concerts each night (except in Austin). The song selections were made by Blue October drummer Jeremy Furstenfeld, who is credited as producer of the album. The band had talked about recording an acoustic album as early as 2004, but the concerts were the first ever full-length acoustic shows that the band had ever performed. The popularity of the acoustic concerts among Blue October fans resulted in the band deciding to perform a nationwide acoustic tour to support the release of the album.
Originally slated for April 26, 2011, the official release date was pushed back to May 10, 2011; however the band released the album on May 3 to fans who pre-ordered the album from the band's website, and the album was available for sale at the band's concerts prior to May 10.
All of the songs on the album had previously appeared on Blue October's studio albums, except for the track Colorado 5591, which the band had played at shows for years but never recorded. The song is about Justin Furstenfeld's experience as a patient in a psychiatric hospital.
