Who gives a flying **** how interesting it looks?
How interesting is it to see a guitarist wank the fretboard? I`ve Been into guitar band music for longer than I have been into electronics, and I`ve seen countless gigs. I find nothing interesting about someone playing a guitar or drums anymore, as I`ve seen it so many times, but I don`t suddenly expect musicians to start playing more than 1 instrument at once just to keep me interested.
The sound coming out of the speakers is paramount, and as long as I can see there is someone playing the sublime music I`m listening to, that`s enough for me.

I thought clubs were about dancing and drinking and munting and celebrating life. I want people to dance, not trainspot me all night to see my every exact move. When did we become dancing monkeys???
As long as the crowd get some indication that your performance is honest then shouldn`t that be enough?

If people aren`t entertained enough by the music and need to come and stare at the performer rather than dance, then the music itself needs a re-think.
