Hmm, thanks for the small bits of insight! I did get my ticket via TicketMaster - I guess they would/should be sending the info?
It's been tough getting a hold of the venue itself (Bitterzoet, Amsterdam) - actually, I couldn't get a hold of them. Sent a few e-mails, tried their Facebook page and even called them a few times. Nothing. It was only after I tweeted to Paradiso that I got a response; Bitterzoet is like a second location for Paradiso - the main club/venue. They couldn't tell me anything when I first contacted them, but after they 'checked', they said it's supposedly after and I would be receiving more info approximately 1 week before the concert.
I'll have a look and see if I can get some info from 'gigs and tours', thanks for the suggestion! Will report back later

Edit: had a look at their website and it looks they've only listed three concerts - the ones in the UK. I'm guessing they're not responsible for concerts elsewhere in Europe.
On TicketMaster, it lists the venue (Bitterzoet) as promoter.
