I was wondering if you know of any radio stations that have D&B shows in
Germany. I want to send out some promotional material to them if I can
locate the correct DJ's?

well, we have a weekly drum&bass radioshow every friday evening from 22:00 - 0:00 CET on HR XXL ( http://www.hr-online.de/hf/hrxxl/ ) called Outbreak.

mr. bassface sascha is the host.
