Chicago's Born of Osiris pioneered a symphonic, keyboard-laden strain of progressive deathcore that set them apart from their peers on albums like 'The Discovery' and 'Tomorrow We Die Alive.' Lee McKinney's technical guitar work and the band's integration of electronic and orchestral elements helped define the Sumerian Records sound of the early 2010s.

Fit for an Autopsy rose from the New Jersey deathcore underground in 2008, led by guitarist and producer Will Putney, who also serves as one of metal's most in-demand studio engineers. Their evolution from straightforward deathcore into a more atmospheric and progressive sound on 'The Sea of Tragic Beasts' and 'Oh What the Future Holds' elevated them above the genre's pack. Vocalist Joe Badolato's commanding presence and Putney's pristine production make them one of deathcore's most critically respected acts.
