I bought the 2cd version of Thunders 'Back Street Symphony' from a Russian seller on Discogs. It was advertised as a European pressing, and when it arrived I was happy, but after winning a copy from a UK seller, closer inspection shows the printing quality of the sleeve to be of a seemingly worse quality than I'd expect for an official release, and it was definitely worse than the UK one I got. Silver pressed CD and everything, but I'd be amazed if it was official. A case of buyer beware I think.
