I wrote an article about the cross-influence between hacking and heavy metal. It covers the use of alternative media, like BBS and AE lines, to convey a hidden truth that is shared between metalheads and hackers. The article is entitled "Hacker Metal" and it is published in Perfect Sound Forever webzine.
For those who remember the early web, Perfect Sound Forever is an e-zine that started in 1993 and has run continuously since. It derived its name from an early Sony/Philips ad designed to convince people to switch to compact disks, and covers all forms of music including a fair amount of metal.
