Formed in 1993, the seven-member vocal band started their humble journey in small NYC music clubs and worked their way up to win the Audience Favorite Award at the 2000 Harmony Sweepstakes national finals in San Francisco. Along the way, they appeared on VH1, Nickelodeon, TNN, NBC's Today Show as well as several appearances on The Howard Stern Show. They performed regularly at NYC rock club Mercury Lounge and their classic rock roots even earned them opening act slots with the likes of The Marshall Tucker Band and The Edgar Winter Group.

Their debut CD, A Cappella's Dead (1999) was called the "classic rock album a cappella has been waiting for" (Recorded A Cappella Review Board). The album features inventive covers of Led Zeppelin, Van Halen, Yes, and Phil Collins' "In The Air Tonight". Their follow-up CD Karaoke Bar Brawl (2002) gained even more praise. Produced by Rockapella vocal percussionist Jeff Thacher, the album was nominated for two Contemporary A Cappella Recording Association (CARA) awards: Best Album and Best Cover Song ("25 or 6 to 4") and was one of RARB's "Picks of 2003" for favorite albums of the year. Karaoke Bar Brawl (named after a true event involving several band members) features loud & raw covers of The Who, Alice In Chains, Queen as well as two original songs.

At the time of their 2008 "farewell" show, the latest album Happy Ending was only partially completed and looked to remain in digital purgatory for good. After taking a long break from performing and recording, the 7 guys got back together to finish the album with producer Ed Chung (Duwende) and staged a reunion show in their hometown back in May of 2013. Happy Ending has put the Ex's back on the a cappella radar - their songs are being played on various radio stations and their lead track "In The Flesh" recently won the annual "Surrogate Bands Pink Floyd Cover Song Contest", sponsored by international radio program, Floydian Slip.
