From the Band :

ERA-DEACAY was suposed to come out on the following monthes, but after talks with Avantgardemusic it seemed necessary and unavoidable to push back the release. We lost quite some time finishing mixing this 4th album, and the mastering is still not over yet.
The album will hit the shelves on September 6.
This decision was not an easy one to make, but we have to be patient to release this album in the best possible conditions. We'll do our best to offer you an exclusive track on our wbesite around June/July.
