Matrix / Runout of Side A here of Human Soul is etched w/"BEIZEL LIVES". But, who is Beizel? I believe that is the name of a founder of an American religious community, but this could be a more inside reference.
This album has on the B-side Matrix / Runout the etched message "RICK AND JOHN BIACTOLBOYS". Is that mean take on some chaps with acne? Actually, a bigger mystery to me about side 2 is what sounds like an unintentional inclusion of a part of a song after the end of "Slash and Burn".
