Welcome to the former Tumblog mind_like_a_laser!
To kick things off, I'd like to (again) post this remarkable 1989 set by Liaisons Dangereuses. It's quite long, but over the course of its three hours it encapsulates much of what I love about dance music. You'll hear synth-pop (Simple Minds - "League Of Nations"), dark electronics (The Normal - "Warm Leatherette"), EBM (Portion Control - "The Great Divide"), hip-hop (Time Zone - "The Wildstyle"), acid house (The Children - "Freedom"), electrofunk (Newcleus - "Automan"), early breakbeat (Renegade Soundwave - "Cocaine Sex"), and early proto-techno and proto-trance (Pete Shelley - "Witness The Change", Grauzone - "Film 2", Logic System - "Unit").
This music is from a time period when artists were out to make a statement and break boundaries; with limited technology and less divide between musical genres, experimentation and invention were the order of the day. This is strong, strange brew, and a harbinger of things to come in the rave, industrial, and trance scenes of the 90s and beyond.
