Well, I got a message from my friend who posted a like about the hungarian hardrock website.http://www.hardrock.hu/?q=node/19560
Here is the raw translation:
Rudolf: "When the Get Your Sting and Blackout Farewell World Tour started, we informed our fans and the media that this will be the last concert series, and the 'Sting In The Tail" will be the last studio album. True, since then appeared in the 'Comeblack' processing on our album, but it's just a side-project was not even contain new songs. However, our library is a huge, huge warehouse, which lies aboard tons of unreleased songs. In the world of vinyl could usually nine tracks on a plate, but of course it is about 14-15 what made to each album, which at that time could not be published. A lot of our materials are, therefore, which of course we do not want to ruin, and we decided, as we end this whole thing, we start to work on this case. I do not know in what form, but be sure that our fans to be put into the hands of those nearly forgotten but once dust and old-old Scorpions songs."
