Monster X about straight-edge:
Explanation from the XXX compilation

For MONSTER X, straight edge is just a name for the human
ability to not need, or do without. Straight edge has never been
"the straight edge", it is not a goal to be attained, it is not an entity
to be worshiped. It is personal, it is individualistic. It symbolizes
all of our ability to look deep inside ourselves - beneath the fashion,
beneath the music, beneath the social & cultural indoctrination and
discover who we are, free from outside influence. Straight edge
is not a source of empowerment in and of itself. It is only a starting
point of understanding what oppresses our thoughts and our
actions. It is the beginning of a self evaluation on ones own terms,
that transcends the accepted standards of our material reality.
