I am not a producer or a DJ. So from a consumer of the material. I would say I think you can have a detroit 'feel' to the music without using classic detroit instuments. theres a lot of music that has a detroit 'feel' to it. it's the string sounds, the high hat programing and the warm percussive percusion. the future feel.
there a hiphip instumental track on roots manuva's 'dub come save me' (apols cant remember the title) which to me is a detroit inspired track, whether mr roots would think that or not, I don't know. but that's how I hear it. more later. just wanted to chip in. rav. Which brings me to this: Can an artist be considered Detroit (or simply techno) ONLY if he or she uses the classic Detroit instruments and melodies/style or is it more about the energy that the music carries?
