The problem is that techno became and still is slightly, over comparmentalised. With producers only making one sound and only listening to one sound.
And as I have commented many times on this forum, inbreeding makes no contribution to evolution.
Going minimal is just another trend and it really is no more superior than any other type of techno.
I`d like to see artists branching out rather than releasing the same record again and again and again and again and again and again and again.
