So the way I’ve been doing live gigs lately is to start with saying hello to the audience and explaining briefly what I have and how it works; so I bring my laptop (on the side), bunch of guitar boxes, matrix mixer, some controllers, dictaphone, monome, and an ipad. Everything is done live, with nothing pre-recorded except some sampled piano and some field recordings. So I’ll explain where the sound is coming from, make a single chord/note, then loop it and explain that I can layer stuff this way, and I’ll start adding bit more on top and stop talking at some point. I feel like this gives the audience some context, and then I also noticed that when starting with short explanation, I get somehow bit more “connection” with the audience, and people are often more open to come say hi after the gig and chat for a while, which for me is usually the best part of playing live.
I’m personally not sure about playing in pitch black, but I wouldn’t go as far as saying that this specific thing is a performance, and that other thing is not. Personally the electronic concerts I love the most are live gigs where I can hear the process, and hear something “live” instead of replaying the album.
