O-Town is an American boy band formed from the first season of the MTV-produced reality television series Making the Band in 2000. As of 2015 the group consists of Erik-Michael Estrada, Trevor Penick, Jacob Underwood, and Dan Miller. The most popular line up also included Ashley Parker Angel, who refused to participate in the 2013 reunion. Ikaika Kahoano was originally part of the band but replaced by Miller after dropping out of the group.

The members of O-Town moved on to solo careers. The most successful member of the group has been Ashley Parker Angel, who was signed to Universal's Blackground Records, and also given his own reality show on MTV, There and Back. Released in 2006, Ashley's solo debut album was heavily promoted, but did not achieve solid sales numbers. In January 2007, he began playing the role of Link Larkin in the Broadway production of Hairspray. Ex-bandmate, Trevor Penick, now professionally known as "Tre Scott", was signed to Mach 1 Music, and worked with established industry producer Eddie Galan. The other band members retained a fanbase and had success in their own right, as evidenced by their Myspace profiles. Erik stayed in the music business and went on to collaborate and co-write songs for other artists. Jacob Underwood went on to start his own country band "Jacobs Loc".  Back in January 2011, rumors were swirling that a reunion was in the works for the band. TMZ reported that Erik, Trevor, Dan & Jacob have returned to the studio to record the follow-up to O2, however, it was confirmed that Ashley Parker Angel declined the offer from the guys. He told TMZ in a following article his explanation. "O-Town was one of the greatest chapters of my life, so when the idea of a reunion was brought to me, of course I was intrigued. However I have made the decision not to be a part of an O-Town reunion. It was a difficult decision, but ultimately necessary to move on with the next chapter of my career."  He has, however, given the guys his blessing for them to reunite without him. When interviewed about his rejection, Erik said that the guys eventually come to terms with it, but admitted "I would just think he would want to come on board and be a part of it ... but he doesn't and that's cool."  The remaining guys continued to pursue the reunion over the next few years, keeping details very private.
