Early days and TraceMyVeins (2004–2005)

Carson attended Billings West High School and graduated in 2005. During his time there, he joined his first band at age 14. Since then he has been in numerous bands, playing different types of music.^[1] Before Escape the Fate formed, Carson Allen had started his own post-hardcore band titled "TraceMyVeins" after leaving previous band "Apathy Drowns Desire" after releasing the EP Farewell Edgewood. The band released two songs that were to be their singles titled "I Wish I Knew How to Quit You" and "This Is What You Get for Helping People?".^[2] After realizing the band wasn't getting anywhere, Allen decided to quit to join Escape the Fate.

Escape the Fate (2005–2006)

Before forming Escape the Fate, vocalist Ronnie Radke, bassist Max Green, drummer Robert Ortiz, lead guitarist Bryan "Monte" Money, Carson Allen, and rhythm guitarist Omar Espinosa were in multiple bands together. Monte Money later created Escape the Fate, and invited Omar Espinosa, who then invited Max Green into the band. Max Green later invited Ronnie Radke and Robert Ortiz, and later recruited Carson Allen.

In September 2005, the band had won a local radio contest judged by My Chemical Romance. The gig awarded them the opportunity to open a show on the band's headlining tour with Alkaline Trio and Reggie and the Full Effect, which subsequently led to Escape the Fate's record deal with Epitaph.

On May 23, 2006, the band released their debut EP titled There's No Sympathy for the Dead.^[3] The EP included two songs that were later on their full-length album, Dying Is Your Latest Fashion. The EP was produced by Michael Baskette and helped earn the band attention from record labels and fans alike. Prior to the EP's recording and subsequent release, Allen left the band to join "Devilyn Alaska"^[4][5] and then eventually On the Last Day.

On the Last Day (2007–2009)

Before joining on the Last Day, Allen had recorded some songs with Devilyn Alaska.^[6][7] When Geoff Walker was removed the band, On the Last Day, in May 2007, Allen had been announced as their new vocalist.^[8] On February 13, 2008, On the Last Day left their record label of Victory Records. On the Last Day then released their second EP called Make It Mean Something, which was released through Torque Records. The album charted at number 3 on the west coast Billboard Heatseekers chart.

On September 2, 2009, On the Last Day announced they were no longer together and were on an "indefinite hiatus".

Me vs. Myself (2009–present)

After the band announced their hiatus, Me vs. Myself was started in 2009 in Seattle by singer Carson Allen, along with Jaron Johnson, Nick Wiggins and formerly Frank Gross till he left the band in 2011.^[9] The four recorded their debut EP "Seasons", which was released February 2010. After playing shows in Seattle, Me vs. Myself began playing shows along the west coast in June 2010. The following January, the band relocated to Los Angeles to work on what would be their Debut LP. On November 29 the band released another EP titled Where I Am...Where I Want to Be, tracked in Buffalo, New York, at the studio owned by The Goo Goo Dolls. The track "Now and Then" was produced by Goo's bassist Robby Takac.^[10]

The band had split in 2012, playing their last show and then deleting their Facebook page with no reason given. They released a statement about the split three years later:

"Exactly 3 years ago, we released "Where I Am... Where I Want To Be"! Since then, we have traveled all over the world individually. Finding who we are. Finding purpose. And finding inspiration. Our paths have crossed occasionally, and every interaction has been magic. We started this band because we all believed in each other, and wanted to share dreams, share adventure, and share our passion for music.. Together! The last show Me Vs Myself played was (also) exactly 3 years ago. The reason that was the last was not because we didn't want to continue, it's because we all needed to experience life a bit more. On January 9th, we will return to the stage that we shared exactly 3 years ago. Play the exact same set. And put the exact same passion into showing the world that Me Vs Myself isn't just a band. It's a hub for people who need hope. A safe place to pour your heart. An escape... The exact reason we started this! See you soon...
