You are right! That the reason iam more interested in trance from '90 to '95 or in that style. I call it Technotrance, because you can hear in the early trance the roots of Techno and Acidhouse of the late '80s and early '90s. The Sound of Frankfurt is my favorite trancesound. Eye-Q and Harthouse and some other labels of that period do it for me: Ralph Hildenbeutel(Earth Nation, etc.), Cygnus X, Resistance D or Oliver Lieb (Spicelab, LSG, The Ambush etc.). Really cool music without (many) borders (and without cheesy vocals ). With hints of techno, acid, ambient, breakbeats.. from low bpms to fast bpms (120-160bpm) its has some feeling of avantgarde. But also the emotional side in this time with Cosmic Baby, Humate, Kid Paul etc. The Sound after '95 was more commercial i think, but I have some nice memories with the trancesound of the late '90s, because it was my guide to electronic music. So i like it too.
