Born of Osiris is an American progressive metalcore band formed in 2003 in Palatine, Illinois, a suburb of Chicago. The band currently consists of lead vocalist Ronnie Canizaro, guitarists Lee McKinney & Nick Rossi, drummer Cameron Losch, and keyboardist/vocalist Joe Buras. Born of Osiris has played at various festivals including the Summer Slaughter Tour (2008, 2009, 2015 and 2018) and the Music as a Weapon Tour 4.
The group underwent several name changes, including Diminished (2003–2004), Your Heart Engraved (2004–2006), and Rosecrance (2006–2007), before finally settling on Born of Osiris in 2007, basing the name on the Egyptian deity Osiris and the tale of his son Horus.
