not sure probably the style of music.
no, i dont think so. and if it was then i think the breaking point must be 2003/2004
yep, that has alot to do with it for sure, but certainly not every time. filteria for example who is a hardware nut =)
yes. production style is for me the thing that defines it.
good question! uhm, i guess not really a hard answer, since style of music seems to be the most defining character; i think the same way a person could make newschool goa he could also make oldschool goa (meaning LESS layers, LESS software-like sound, using hardware sequencers and synths for sure will help here)
