well, being in a live electronic band (albeit a verrrrry small one) I thought I'd throw in my two penneth.
For me its about exactly what an electronic band can pull off live (i.e. what they're actually doing) and then what sort of a performance they do. In terms of structure our live stuff is pretty much as our studio stuff, I'd say 85% of our synths are generated live on stage which leaves is free to tweak synth parameters live or play the synths live. For me its soooooo easy to see when a person's miming.
What I dont want to see on stage is a bloke hunched over a laptop pressing a mouse with about as much passion as though he's checking his emails
The exception of course if when I went to see Kraftwerk..
This is us in Liverpool last month...hey yup its a plug but its a good illustration of what we do
