They are quite big. I visited gallery yesterday. More precisely, I was standing behind door as it was closed. hah. Well, it was only day I could be (and was anyways) in Helsinki. My criticism would be that I'm personally quite bored with "standard" exhibition concept, where you got huge white gallery walls, and then one piece in middle. Next wall same thing. Next wall, few words on large helvetica type.
I can't be only one, who'd prefer some another format for exhibition. Even utterly cluttered gallery, where every empty slot has been taken into use. It feels little too much tied to old fashioned laboratory-esque museums, where huge white rooms display perhaps just one piece per wall. I'd like to see different approach.
That all said, anyone in Helsinki, I do suggest to check this out while they can. It's no often when sort of experimental music related artists are on real galleries.
