You might be right although I prefer decent post rock live over generic metal bands live.
I do love post rock though and would rank Russian Circles and sleepmakeswaves among my favorite live bands. I haven't seen too many other post rock bands but Mono, Beware of Safety I've enjoyed. Pelican was a little flat when I saw them.
