To mark the then forthcoming world premiere performance of Roger Waters' Ca Ira, being held in Poznan, Poland, SonyBMG released a special limited Polish edition of the album on August 21st, complete with custom artwork on the front and back of the package.

As you will see from the pictures to the right, the front has the design used in the concert's promotional materials, and promotes the concert that was held on Friday night (August 25th).

On the rear of the CD, there is a pre-printed autograph and dedication "To my Polish friends" from Roger himself.

With limited availability in stores, the edition seems to have been principally created for sale at the concert itself, although some stores in Poland have also been stocking this. No doubt with the help of the local radio station's name on the front cover, the price of the double album was fixed at around 10-15 euroes, so has apparently sold strongly.

As we noted a couple of days ago, the show itself was a huge success, and involved several hundred artists - a number of costumed actors, an orchestra, choir, stuntmen and opera singers - along with beautifully designed sets and scenery.

There are plans to stage at least 16 open-air productions of the opera in venues across Europe during 2007, according to the promoters. Naturally, as we get more detail on the additional shows, we will let you know straight away - so please don't email us to ask when and where they might be. Full information will be on the site!

Our thanks to Marek Grzesiak for his help with this information.
