3. EXIT's roots formed in 1997, when teenagers Courtney and Affa bonded over their love for The Beatles. In 1999, Pam and former singer Nikki signed on and by 2001, EXIT had established themselves as a no-frills U2 tribute band. Compelled from the start to write their own music, the band began gradually filling their sets with original tunes. EXIT soon proved to be a strong musical force within the Los Angeles music scene. Five years of experience later, the band has a new vocalist, Trevi, and is committed to honing their original sound, writing prolifically and performing more powerfully than ever before.

For a young band, the influences that underlie EXIT's foundation are sturdy - U2, The Beatles, Peter Gabriel, Daniel Lanois, Pink Floyd and The Who inspire elements of EXIT's sound. Great respect for this music and the high expectations the band sets for itself show through in the quality of the songs and the passion revealed onstage.

In a short time and mostly through live performances, EXIT has captured the interest of the media, music industry and fans worldwide. In November 2005, EXIT was brought onstage by U2 to play “Out of Control” at the sold-out Staples Center in Los Angeles. The band has been featured in the Los Angeles Times, Blender Magazine and on the TV show EXTRA. EXIT has performed in venues near and far: The Whisky-a-Go-Go, The Viper Room, The Key Club, The Rock ‘n’ Roll Hall of Fame in Cleveland, El Mocambo in Toronto, Canada, Sunset Station in Las Vegas, and Ameristar Casinos in Mississippi and Iowa. In December 2003, they had the honor of playing to USO and NATO troops on a tour of Bosnia and Kosovo.

A desire to share their original material with their growing fan base compelled the band to enter the studio in early 2003. Written, produced and financed independently, the self-titled EP was finished just in time for a trip to Cleveland, where the songs made their debut on broadcast and Internet radio, thanks to Todd Richards of WBWC, who interviewed the band on his show.

After a busy couple of years spent traveling, gigging and songwriting, EXIT returned to the studio in October 2006 to record their second EP due for release in December. The band anticipates the production of a full-length album in 2007. Trevi, Courtney, Affa and Pam are currently writing songs and performing in and around Southern California.
