whoever you are, being sarcastic really doesnt work here. yes post rock is instrumental. Whatever my intentions to have a vocalist for a "post rock band" isnt in your great interest. i hope you understand this and be mature about it. thanks
yeah dude, whatever he wants to do is entirely his creativity ,theres no right or wrong perceptions of post rock, its boundless, anyway good luck in ur search, i myself is in a post rock band currently experimenting, looking to expand.. =(
