There is only a single song in existence and it’s not technically an Excarnation song. This is a live version of “Gaping Chest Wound” by the band that became Excarnation a few months later: A Crown Disowned.
There is no surviving record of Exarnation, a death metal/hardcore band from Daytona Beach, Florida. They weren’t around for very long. Danny would stop drumming halfway through most of the songs because he forgot the transition and Derrick would throw his guitar on the ground and leave the show. They had a song about a woman giving birth to a full-grown horse: “Dormant seeds of equestrian breeds. Young woman, you have given birth to a steed.”
