Trance and progressive house DJs can be listed and found here. Any listing that pertains to this genre but is not a DJ site should be directed to Arts/Music/Styles/Trance. Trance is a form of electronic music that is made to get people dancing. What distinguishes trance from house or techno is the evidence of emotive key changes, more layering of sounds and, most of the time, better quality production. Progressive house is a subset of trance that is generally more minimal and closer to house than it is to techno. A DJ who doesn't know if they play trance or not most likely doesn't!
