Black Cobra are a sludge and doom metal duo from Los Angeles, California, formed in 2001 by guitarist/vocalist Jason Landrian and drummer Rafael Martinez, who generate a surprisingly massive sonic footprint for a two-piece. Their early releases Bestial (2006) and Feather & Stone (2007) established a heavy, groove-oriented sound drawing equally from doom, sludge, and noise rock, and the band maintained a prolific output throughout the 2000s and 2010s with releases on Southern Lord and Season of Mist.

Black Sheep Wall is a Moorpark, California sludge and doom metal band formed in 2006, named after a StarCraft cheat code. Their minimalist, downtuned approach draws comparisons to Eyehategod and early ISIS, delivering some of the heaviest and most oppressive post-metal to emerge from the American West Coast. Notable releases include No Matter Where It Ends (Season of Mist, 2012) and I'm Going to Kill Myself (2015), albums that pair crushing riff architecture with extended dynamic tension.

Bloody Hammers is a gothic doom duo from Transylvania County, North Carolina, formed in 2012 by singer-songwriter-multi-instrumentalist Anders Manga and keyboardist Devallia, his wife. Named after a Roky Erickson song, the project channels Black Sabbath's heaviness through a gothic and occult rock prism, placing it alongside Ghost and Uncle Acid & the Deadbeats in the early 2010s occult rock revival. After signing to Napalm Records in 2014, the duo released a consistent run of albums through the decade, including Black Magic (2016), The Summoning (2019), and Songs of Unspeakable Terror (2021).

Bongzilla is a stoner, sludge, and doom metal band from Madison, Wisconsin, formed in 1995, whose catalog is among the most explicitly cannabis-themed in American heavy metal. The band released a string of albums on Relapse Records—including Stash (1999), Apogee (2001), Gateway (2002), and Amerijuanican (2005)—before entering a hiatus from 2009 to 2015. After reforming and returning to the touring circuit, they released their sixth studio album Dab City via Heavy Psych Sounds in June 2023, cementing their status as seminal figures in the American sludge underground.

Brimstone Coven is a doom metal and occult rock band from Wheeling, West Virginia, formed in 2011 by guitarist Corey Roth, who assembled the group around vocalist 'Big John' Williams and a core of local scene veterans. The band's self-released early material led to a deal with Metal Blade Records in 2014, with their Metal Blade debut appearing that same year and Black Magic following in 2016, both records rooted in the Black Sabbath and Pentagram tradition with additional influence from Led Zeppelin and early Pink Floyd. They later moved to Ripple Music for The Woes of a Mortal Earth (2020).
