Difficult though it may be for the old vanguard to accept, I believe most if not all vital innovation in the jam band format is coming from the industrial electronic musical sector.
Autechre are a great example of one such band who - late in their careers - have released dozens of hours of improvisatory and fresh takes on old material performed live and categorized by the year and city in which the performances took place.
These recordings are then - of course - fawned over and endlessly analyzed by obsessive devotees and electro-hippie freaks who collect, distribute, and bootleg them along with whatever other unreleased or previously unknown material they can independently gather.
It is, as ever, a brave new world, and change is confusing, but if you listen with an open mind you’ll surely find yourself entranced by Autechre’s Psycho-Electronic Experimentations …. Peace and Love✌️
