New research reveals that guitar skills in extreme metal music are more linked to male competition and status than to attracting mates. The study, focusing on heterosexual male guitarists, suggests that technical proficiency in guitar playing serves more as a display of dominance among peers.
I’d question the dominance thing as a whole. If you have two male pro metal shredders in a room they will not assert their dominance over the guy who just learned his first chord. Also they will not try to mate anyone… they will just shred until they get tired or kicked out.
