Four Year Strong is a five–piece American power–pop/post–hardcore band from Worcester, Massachusetts. 3/5 of the band were in the original lineup that dates back to 2001. Dan, Alan and Jake all attended Doherty Memorial High School in Worcester and met through mutual friends. After the departure of the original bassist some 2 or 3 years after formation, they met Joe and asked him to fill the gap. Their early work never included any keyboards or synthesizers, but after a while they began to incorporate it into their music. The band cycled through many keyboardists, but recruited their current keyboardist Josh Lyford in late 2006.
