Self-described as a "desert pop" band, Peoria, AZ-based the Format materialized around two friends, vocalist Nate Ruess and multi-instrumentalist Sam Means, in the early 2000s. Taking influence from '60s music to craft their own spirited indie pop melodies, the pair were barely in their twenties when they laid down a five-song EP with producer Bob Hoag. Next thing they knew, the first track from that EP -- the aptly titled "The First Single" -- found its way onto local radio and became a minor hometown hit. By the spring of 2002, the Format had caught the attention of various major labels and chose to ink a deal with Elektra. They wrote songs together via acoustic guitar, and their debut full-length, Interventions and Lullabies, was issued in October 2003.
