Cold War Kids are an indie rock band from Fullerton, California, USA. Band members are Nathan Willett (lead vocals, piano, guitar), Jonnie Russell (guitar, vocals, percussion), Matt Maust (bass guitar), and Matt Aveiro (drums).
The band started in 2004 in historic downtown Fullerton in guitarist/vocalist Jonnie Russell's apartment above the restaurant Mulberry St. Ristorante (their first EP title). The band relocated to Los Angeles and began recording their first demos, and after signing to Monarchy Music, the band released their debut EP Mulberry Street in the spring of 2005. The band toured extensively in 2005-2006, which ultimately created internet buzz amongst the blogging community. While touring, the band released two more EPs, With Our Wallets Full and Up in Rags in 2006. In the summer of 2006, Cold War Kids signed to Downtown Records (home to Gnarls Barkley, Art Brut) and released their debut LP Robbers & Cowards that fall.
