Tickets will be available starting September 10 2007 at promotional prices of 25 leva until the end of the month. Later the price will go up to 30 leva.

The concert in Sofia will be part of the bands’ first joint tour Hellish Rock 2007/2008. The tour starts on November 16 2007 in Budapest. It is in support of Halloween’s new album Gambling with the Devil.

Halloween and Gamma Ray’s getting together is not a coincidence. Gamma Ray’s founder Kai Hansen is a former Halloween band member. During the tour he will play with both bands.
