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.
