Hey, you started a thread a few weeks ago looking for some post-rock bands with vocals, right? Well, have you ever heard of Doí? In reality they don't use vocals all the time, but they are very good, so I guess you could like it. They are a danish band, and I don't know much about them, except that they released a pretty good album in 2006 ("Sing The Boy Electric"). If you're interested, check their MySpace or download their songs on their Last.fm page. As you live in Belgium, maybe it's easier for you to find out more about them... Well, hope you like it.
