DJs are known to speak with their hands. Producers, on the other hand, tend to create what they can't express through words with their sounds, and in the electronic music realm, the weight of the music can render words useless. That's not to say that producers aren't using their voices... it's quite the opposite. Kaskade recently got a Grammy nomination for "Atmosphere," a track that was so personal that he lent his own voice to the song. He's not alone, though; many producers over a number of electronic genres have stepped up to the mic to express themselves vocally. This is nowhere near a complete record of a producer using their own voice on their songs, but it's a great look at the many ways their vocals have been incorporated.
