After the dissolution of Coal Chamber, vocalist Dez Fafara formed DevilDriver in Santa Barbara, California in 2002, pursuing a more aggressive direction rooted in groove metal and melodic death metal. Albums like 'The Fury of Our Maker's Hand' and 'The Last Kind Words' showcased a band far heavier than Fafara's nu-metal origins suggested, driven by relentless double-bass drumming and interlocking guitar harmonies. Their ambitious country-metal covers album 'Outlaws 'Til the End' revealed an unexpected creative range.

Los Angeles' Fear Factory were industrial metal visionaries who merged machine-gun precision riffing with Burton C. Bell's groundbreaking clean/harsh vocal dichotomy, creating a template that countless bands would follow. 'Demanufacture' and 'Obsolete' remain towering achievements in the fusion of extreme metal and industrial electronics, their dystopian sci-fi themes proving eerily prescient decades later.

Five Finger Death Punch stormed out of Las Vegas in 2005 and became one of the 21st century's biggest hard rock bands through sheer aggression and arena-ready hooks. Vocalist Ivan Moody's blend of melodic singing and savage screaming powers anthems like 'The Bleeding' and 'Wash It All Away' that dominate rock radio and military playlists alike. Love them or not, their brand of groove metal and hard rock has sold millions of records and fills amphitheaters across the globe.

Hatebreed have been the soundtrack to channeled aggression since Jamey Jasta formed the band in Bridgeport, Connecticut in 1994. Their brand of metallic hardcore, built on motivational lyrics delivered over crushing mosh-pit anthems like 'I Will Be Heard' and 'Destroy Everything,' became a global phenomenon. Jasta's ability to transform hardcore rage into something genuinely empowering has made Hatebreed one of the best-selling and most enduring bands in hardcore history.

Oakland's Machine Head have been a pillar of heavy metal since Robb Flynn founded the band in 1991, with their debut 'Burn My Eyes' becoming a groove metal landmark. Their 2007 masterpiece 'The Blackening' marked a dramatic creative peak that earned universal acclaim, and through lineup changes and stylistic shifts, Flynn's unrelenting vision has kept Machine Head a vital and confrontational force in metal for over three decades.

Machine Heed bring a riff-heavy approach to modern metal that draws from the groove and thrash traditions of their namesake's sonic territory. The band delivers crushing live performances built on tight, aggressive instrumentation and a no-frills attitude toward heavy music.
