Do you mean live bands playing music typically made with computers? I've seen various bands attempt various styles of electronic music over the years (one that comes to mind is The New Deal out of Toronto) but I find that, most of the time, electronic music sounds best when produced in the studio.
When the producer chooses the right parts! I remember hearing one track I'd recorded for a house producer on the radio one night (for the session he let the tape run and I blurted out a bunch of different ideas). I thought, "Hmm - that sounds familiar". Then I realised it was me playing and at one point I thought, "What?! He chose that part?!!"
