what do I want to wear on stage?
General rule for me, all black. last gig I wore my Resident's t shirt, looked great, black shirt, guy in tux and top hat with eyeball head printed on it, bad idea. So much thick rubber on that shirt (the white ink, high quality!) it stuck to my bass and I couldn't move it around, it was like a non-skid surface, very very annoying. I will never wear it on stage again unless I'm only playing the Stick, which is highly unlikely, I usually have at least 3 different bass instruments with me.
Anyway, seems to me this comes down to 2 principles, on on hand you should never let anyone else tell you what to wear, in a perfect world, I have always felt that was true and important, especially when making art, which I do for freedom of expression. On the other hand, there's nothing wrong with dressing up if you want to, whether it's in a tux or a suit of armor. if you wear a black t shirt with a skull on it, with batwings, say, that's fine, it says "I like fantasy", if you dress like Gene Simmons, it says "I AM fantasy". a little more serious.
I spent years clinging to the notion that it should not matter what you look like, or how you dress, and I still hold that to be true, inherently it doesn't matter, if you are choking on some food and a stranger gives you the Heimlich maneuver and saves your life, you are not going to care what they look like, how they are dressed or even how they smell. when it comes down to it, it has no real importance. That said, people do judge you based on your appearance, and at some point I decided I wanted to control how I appeared, and not just wear random clothes, I will dress in clothes I think are cool, and that make me look "cool" according to my standards, so I am putting some thought into my appearance now, however, I still wear what I want, and do not want to be told what to wear.
On stage; when the grunge movement started and musicians had the "no-look" look, this was a rebellion against glam rock, and an understandable one, but whatever you wear makes a statement. My younger self would probably be shocked to hear me say now, you should look like you're in a band, whatever that means, when you're on stage. (unless you don't want to). How one dresses can be influenced by where you are going to be. I play sometimes filling in with a Bowie tribute band, the singer dresses up, in a nice jacket and button shirt, something Bowie might wear, most of the guys just wear t shirts and jeans, for that act, they should really dress up a little bit I think, put on a show, it's Bowie, not a Weezer cover band, but in a biker bar, you don't wanna dress up too much and alienate the crowd, most of whom want the early rock and roll Bowie, and less of the new-wave stuff. These are probably guys who liked Queen in the 70's and had no idea that Freddie swung both ways. Might be hard for kids today to understand what life was like in the 70's, most popular music fans had no idea Elton John was gay. They just accepted that rock stars liked to dress up in showy outfits and put on a show. I wear all black on stage generally. I've taken to wearing a hat, my hair isn't that thin yet, but lights are unflattering and create unfair illusions as to how much light normally bounces off my scalp. Cameras are unkind.
I wish I could get my band to dress up a little more, we play fusion jazz rock. I'll see if I can dig up a couple of stage photos, incidentally last time I saw Stanley Clarke perform live, last year, I recall he was wearing jeans and a t shirt.
In conclusion, wear whatever the hell you want, don't let anyone tell you what to do, but understand the consequences of your choices and live with them. you might find it's fun to dress up a bit. the businessman in his suit and tie, is in as much of a costume as the punk with the green mohawk.
live at the Middle East the belt is for the Chapman Stick. the boots are for show. very comfy too. Earth Wind & Fire t shirt.
live outside in Harvard sq, years ago busking for bucks, pays too look poor I guess, not that it helped. tough to wear all black outside in the summer :/
I would never wear that much colour anymore on stage.
