Long Island-based Bayside formed in the winter of 2000 and released the Long Stories Short EP the following year. The band soon signed with Chicago powerhouse Victory Records and released their debut full-length, Sirens and Condolences, in January 2004. Bayside took early advantage of community websites like Friendster and MySpace to promote their music, making them an early pioneer in what has now become a standard practice for online music marketing.

Bayside released their self-titled sophomore album in August 2005, but the resulting tour turned tragic when their bus hit a patch of ice and flipped over en route to Salt Lake City. Drummer John “Beatz” Holohan was killed in the crash, and bassist Nick Ghanbarian was severely injured. Bayside took some time off following the accident, only to press onward as a duo (Anthony Ranera on vocals and guitar; Jack O'Shea on guitar) in honor of their friends. The live DVD and accompanying Acoustic EP was released in Feburary 2006.

Bayside is currently comprised of Raneri, O'Shea, Ghanbarian, and drummer Chris Guglielmo.
