The Ophidian Trek, to be released in the autumn, features footage shot during their European tour and at the Wacken festival this year. It's their second live DVD following 2010's Alive.

Drummer Tomas Haake says: "It's been four years since the release of Alive, and with the band celebrating 25 years, we just had to get another one of these puppies out there.

"We're super-proud of how it came out. Talented photographer Anthony Dubois has really done a stunning job with it. Hope you guys dig it - and here's to another 25, or maybe just a little less!"
