The NIN thread got me thinking about one of the drawbacks of solo performance, which is that the visual effect tends to lack a strong impact. As a guitarist, it's pretty easy to just sit on the stool and work the guitar and pedals. And that's not too interesting to watch, even when it's Fripp. It's tempting to invite other musicans, especialy percussionists who could hang with anything I might be doing without a lot of rehearsal, to sit in if only for the added visual impact. So what are your thoughts regarding how you approach making your solo looping gig more visually engaging?
