In North America the album will be released on Astralwerks April 6th. Expect to pay in the region of $25 for the special editon in the USA, $30 in Canada. Will post if I hear of a better price elsewhere.
The blog is celebrating one year online! Actually it was a year to the day yesterday I made the first post, but I forgot about it!!
Amazon.com among others are taking pre-orders for the best of stating an April 6th release in the USA. Assuming this is correct, that should mean an April 5th release in the UK.
