Storm Corrosion is seemingly available to purchase and download now in Poland, from the Polish iTunes store. It’s been available there since April 11th, even though the actual release date for the album is May 7th in Europe, and May 8th everywhere else. I’ve posted a screenshot below of the listing, and you can access the page here, although only people who reside in Poland and have a Polish credit card will be able to buy & download the album now. However, if you view the listing on iTunes desktop client (not using a web browser) you can access new samples.

You can pre-order the physical versions of Storm Corrosion (on Blu-ray/CD & Vinyl) here.
