The band had this to say, "While putting the finishing touches on the material for our next album, we have to inform you that guitarist and original member Martin Henriksson sadly but amicably left the band a couple of months ago."

Henriksson says, "I recently quit the band. I feel I have lost the passion for playing music, and Dark Tranquillity deserves to have members that are 100% committed to the art. Therefore I decided it's in everyone's best interest to step aside and leave the band with the best possible ability to grow and get even stronger.

"I've had 26 years filled with wonderful memories and we made a lot of great music together, and for that I'm forever grateful. Thanks to all the fans, crew and other people involved that supported Dark Tranquillity through the years!"

The band has yet to reveal Henriksson's replacement but they have confirmed a tour dates across the world beginning with an appearance at the Feel The Noise Festival later this month in Austria and a series of European festivals this summer followed by a North American tour in November and December.
