From Therion website:

"We have since some months a new drummer called Petter Karlsson and after rehearsing for a while with him, playing both new and old songs, I must say it sounds really good. (...)
We have also rehearsed with Matts Lev'en and it sounds really cool, prepare for a different Therion sound un the upcoming festivals and tours!

Regarding singers there is also a big change. As you all know Sarah Jezebel Deva have been singing with us live for quite some years. Well unfortunatly she will not be able to go with us this time due to some health problems. We are very sad about this, but have found a replacement called Karin Fjellander who is a young swedish soprano that have a background as a viola player, but who now study classical vocals since some years.

We have made a death metal project in secrecy called "Demonoid" that will be released in July! It is mainly Kristian and Johans project musically, but I contributed with some riffs, sang on it and made the lyrics".
