The punk-inspired quintet Yellowcard formed in Jacksonville, FL, in 1997 but didn't solidify their lineup until a move to southern California in early 2000. Comprised of vocalist/guitarist Ryan Key (who had briefly played with Cali-based Craig's Brother), vocalist/violinist Sean Mackin, guitarist Ben Harper, drummer Longineu Parsons, and bassist Warren Cooke, the band officially debuted on wax in 2001 with One for the Kids (Lobster) and returned a year later with the Underdog EP for Fueled by Ramen. The group had a really big year in 2003, replacing Cooke with Pete Mosely (of Inspection 12), signing with Capitol, issuing Ocean Avenue on the label, and heading out for a series of Warped Tour dates with the recently added Mosely replaced by Alex Lewis. Fall and winter found Yellowcard hitting clubs with acts like Matchbook Romance and Less Than Jake.
