There's your startup idea then. A high quality independent retailer for underground rock music. Boomkat for guitars. Two problems: 1) Rock music is much more controlled by the big four labels. I checked the latest album from Lamb of God, the most fucked up metal band I could remember off the top of my head: they're on sony. On the other hand, Sunn O))) are on an independent label and they're pretty well known. Maybe lamb of god are more mainstream than I remember. 2) Rock music lacks electronic music's mainly nerd-based audience. While there are undoubtedly a lot of nerds in the metal scene, they lack the raver's inherent kinship with machines. Also, there isn't the same DJ culture, which is perhaps the most common reason why buyers of electronic music demand quality.
