The they in question is a he, who scours the Internet and then produces CDrs and DVDrs of everything he downloads. Much of this is other people’s hard work, however, that said, the DVDs he produces are, from a completists point of view, the best out there as he more or less tracks down everything that’s on the web.
FAB’s output is also very prolific averaging about 15 to 20 new releases a month.
Personally, I’m a fan and collector of his DVDs but not so of his CDs.
