Yellowcard is a pop punk band formed in Jacksonville, Florida in 1997, and based in Los Angeles, California since 2000. Their music features a rare contribution to the genre, incorporating the use of a violin. The band is currently not active as they are on a self-described "hiatus".
History
Early years
The band released their first album, Midget Tossing, in 1997. While Sean Mackin was featured on some of the songs, he was not a full-fledged member yet, as he still objected to many of the band's messages. Where We Stand, their second album, featured the same lineup as Midget Tossing, and Mackin was featured on more songs. Soon Ben Dobson lost interest in the band and left. He was replaced by Ryan Key (vocals & rhythm guitar), a local of Jacksonville who was playing in a band called Craig's Brother. This changed the band's music style drastically, from hardcore punk to pop punk. It also changed most of their fan base, leaving them with a new beginning and a fresh start as a band.
