I've always considered the visual aspects of any performance equally as important as the sound itself. In the visual aspect, I look at the overall appearance of the rig itself, no wires running across the floor other than the power cord, line(s) to the PA, and some pedals - that's it - bare minimum. All other wires are concealed by my console and completely out of sight of the audience.

Lighting is of paramount importance and should always be appropriate. For me, flashing, glaring lights are out of the question. My lighting of myself, the sign and keyboard are all soft.

Dress code: I book a lot of jobs and every person that has ever booked me has commented on how my appearance always has been very professional. I'm always amazed at performers that show up in dirty work boots, jeans they wore on a construction job earlier in the week, some weird tee shirt, and maybe a grungy looking cowboy hat. In my case, it's a neat hair cut, highly polished, black shoes, black slacks, satin shirt (cooler months), guyabera shirt (warmer months), matching tie, silk vest, cuff links, gold tie clasp, clean shaven, etc...

As for standing up while playing the keyboard, NAH! Lawrence Welk sat down, Little Richard sat down, Jerry Lee sat down, jumped around, and did some crazy crap. Lots of guitar players sit on stools, and lots of other performers sit while performing. I stood for years while playing and no one ever said I looked more professional because I was standing, and no one ever said I looked less professional when I began sitting down while performing - it doesn't a make a bit of difference.

Cheers,

Gary
