Bongzilla is a stoner metal band from Madison, Wisconsin. As their name suggests, most of their material is related to marijuana and promotes its legalization. The band formed in 1995, and over the next three years recorded and released a dozen songs on EPs and split singles. In 1998 they signed to relapse records, and have since released four studio albums and a live album through the label. Since the seeds were planted in the mid-90s, Bongzilla have been sowing Madison, Wisconsin's rich soil with their homegrown, psychedelic sludge.
