Yellowcard is an American pop punk/alternative rock band formed in Jacksonville, Florida in 1997, and based in Los Angeles, California since 2000. Their music features the use of a violin, unusual for the genre. They are best known for their songs "Ocean Avenue," "Only One," "Lights and Sounds," and "Light Up the Sky," and "For You, and Your Denial." The band went on to a two-year hiatus then announced their return in August 2010 and released their latest album, When You're Through Thinking, Say Yes, in mid-March 2011.

Yellowcard was formed in 1997 in Jacksonville, Florida after meeting at Douglas Anderson School of the Arts. The band released its first album, Midget Tossing, in 1997. The original members were vocalist Ben Dobson, guitarist/vocalist Todd Clary, violinist Daniel Soans, guitarist Ben Harper, and drummer Longineu W. Parsons III ("LP"). While vocalist/violinist Sean Mackin was featured on some of the songs, he was not a member yet, as he still objected to many of the band's messages.
