Years ago, before I had even heard of Elektron (and when the 
was completely inconceivable to my tiny brain) I started a project with a friend where the only rule was “no computers or backing tracks” - everything was to be played or looped live.
We made one demo and played one gig ever, then moved on to different projects and never did any more. During lockdowns, my friend has finished a full record using bits of old demos and new stuff.
All sounds come from some cheap Casio keyboards, a Roland Alpha Juno and a Korg Ms2000 by way of Kaoss Pads and some guitar pedals.
