if you want it doom and autumn, there's Desertfest in Antwerpen:

there used to be also the
Incubate festival in Tilburg, which I would have highly recommended. Unfortunately it has been cancelled because they had a major budget cut problems. That's too bad, didn't know about it until now when I googled about the lineup for this year ...
