Based in Rancho Bernardo, Bandemic is a high-energy cover band that plays a wide variety of rock and dance music. It started when guitarist Walker Force (aka Jammer) and singer/guitarist T. Idol formed the Undecided Band in early 2003. They performed under the same name in and around San Diego until early 2007. In 2007, the Undecided Band finally decided on a name.
The band later recruited Paul Klecka on bass, Marlon Figueroa on drums, and singer Sheena.
