DO: Include Detroit DJs and Artists. Genre not important as long as contemporary with some electronic elements. e.g. Slum Village, but not a Detroit Polka band. Include International artists and DJs whose music is either Detroit influenced, or is interesting and enjoyable in it's own right and not too far from the core focus on electronic music. E.g. Tortoise and Autechre were good DEMF bookings. Include the best proponents of new dance music genres. E.g. Burial would be a good booking. Give him a Luchador mask to wear if he's still feeling bashful.
DON'T: Book Trance DJs. Trance music -- regardless of nation or city of origin -- is the opposite of Techno, and the opposite of good music, for that matter. Book a DJ/Producer who don't actually make the music they release under their names. Book any Big-room, Ibiza-DJing, Coked-out, Primadonna Bullsh1t DJs. Now it's tough to balance financial prudence with artistic integrity, and arguably Paxahau has mostly done OK. But the only rightful place for Benny Benassi at DEMF would be in a dunk tank.
