Go Betty Go is a Los Angeles punk rock band. Their Latina origins influence their music (most obviously through their Spanish lyrics). Following their well-received debut EP Worst Enemy, Go Betty Go continued their impressive rise with a series of non-stop coast-to-coast appearances, including appearing on the Warped Tour. With the release of Nothing Is More, Go Betty Go delivers on the past four years of work. Produced by Flogging Molly's Ted Hutt, Nothing Is More is leavened with several differing moods and sounds. Themes of desperation and hope are explored, particularly on the tracks "Saturday" and "Runaway". "The Pirate Song" goes off the beaten path with a tongue-in-cheek magnetism, enhanced by the Pogues’ James Fearnley’s accordion and Hutt’s banjo. A handful of Go Betty Go stage show staples are captured "Crumbling Down", "Donde Voy" and "No Hay Perdon".

On February 13th 2006, the band announced that Nicollete Vilar had left the band, confirming rumors to that effect. On May 30th 2006, Emily Wynne-Hughes joined the band as their new lead singer.
