I’d say find another DJ or friend who’s passionate about D&B and talk to them about what they like. Get away from the internet and speak with a live, breathing human being. I’m a firm believer your selections will have more soul for it. Nothing like hanging out with a friend and sharing music you like in person.
If you dig on the internet, another technique is to look for information instead of mp3s. Search for interviews, wikipedia, blogs and magazines. They’ll usually mention tons of other interesting and related artists and trends. These tips might be a bit old school, but I bulk listening on the internet usually means wading through tons of crap. Even with great tools like soundcloud and mp3 stores, my brain and ears go numb. Sorting through ideas keeps me inspired.
