Hehe, my gf's has been running around here in brussels as well when he was on a visit here.
Don't know any of the bands you mention Satis, but that probably won't surprise you. I hardly visit any concerts, might visit Hooverphonic and Admiral Freebee this holiday at theirfree concerts in my hometown.
And Marktrock is close, it's a new formula but don't know their line-up yet, i'm really cheap when it comes down to me paying money to see a band though.
