If you really don't want any sheen, consider a cotton twill. (That top's a slightly odd colour, but you could dye cottons if you wanted to.) You could also consider layering a wicking undershirt beneath it to help with sweat.

thanks for the suggestion. do you think i should use a different fabric for the top, black neck part? i know that i'll probably use fabric gel or something to draw the soundwaves...
