Fu Manchu emerged from Orange County, California in 1985, initially as a hardcore punk act called Virulence before reinventing as a stoner rock band in 1990 and aligning with the Palm Desert scene alongside Kyuss and Queens of the Stone Age. Their breakthrough came with The Action Is Go (1997), widely regarded as a landmark stoner rock album, built on heavily distorted mid-tempo riffs, surf-inflected melody, and lyrical obsessions with muscle cars, skateboarding, and 1970s B-movies. More than a dozen albums deep, including California Crossing (2001) and the double album The Return of Tomorrow (2024), Fu Manchu remain one of the most consistent and prolific acts in the genre.

Their platinum-selling album 'Something Like Human' helped define the mainstream rock sound of the era alongside Creed and 3 Doors Down.

Full of Hell formed in Ocean City, Maryland in 2009 — taking their name from an Entombed song — under vocalist Dylan Walker, guitarist Spencer Hazard, and drummer Dave Bland, initially working in a hardcore and powerviolence framework before absorbing death metal, noise, and experimental elements over successive releases. Their catalog includes six studio albums, from Roots of Earth Are Consuming My Home (2011) through Coagulated Bliss (2024), alongside notable collaborative records with Japanese noise artist Merzbow, sludge outfit the Body, and doom act Primitive Man. Their 2017 album Trumpeting Ecstasy, released on Profound Lore, is widely considered a high point of contemporary extreme metal's intersection with noise and grindcore.

Fuming Mouth formed in Milford, Massachusetts in 2013 and play a muscular old-school death metal style filtered through hardcore aggression, releasing their debut full-length The Grand Descent (2019) on Triple B Records before signing to Nuclear Blast for the EP Beyond the Tomb (2020). The second album Last Day of Sun (2023) was informed in part by vocalist and guitarist Mark Whelan's battle with leukemia, lending the record's crushing death metal framework a particularly urgent personal resonance. The band has toured alongside The Black Dahlia Murder, Frozen Soul, and August Burns Red.
