Limited yellow colored vinyl LP pressing. Acid Mammoth is a doom metal band from Athens, Greece. The band was formed in 2015 by Chris Babalis Jr. (vocals & guitars) and Dimosthenis Varikos (bass), good friends since high school, with a deep love for Sabbath and other heavy music. They were quickly joined by their very good friend Marios Louvaris (drums) and Chris Babalis Sr. (guitars), Jr.'s father. Acid Mammoth is more than just a band of friends. They are a family.
