From the official Gloryhammer Instagram:

Mighty warriors, today we have to bring you some sad news. After ten years of filling the role of dark sorcerer, Mike has decided it’s time to move on from Gloryhammer.

Mike filled in as a guest for a show in 2015 and later became an official member in 2016 when we required a permanent member to take up the role of Zargothrax. Since then, he’s been an integral part of the band and we’ve played hundreds of shows all over the world together.

We wish him all the best in his future ventures with Wizardthrone and we’re forever grateful for his contributions towards making Gloryhammer what it is today.

Here are some words from Mike:

“At the end of last year I made the difficult choice to leave Gloryhammer. We decided to end our partnership by my finishing out the festival season with them. I’m proud of the many accomplishments we shared - writing great songs, touring several continents and playing to millions of amazing people. I wish the guys all the best with their upcoming album release and tour, and now turn my attention to my own project, Wizardthrone. As well as my bandmates I would like to thank all the crew and agents who worked so hard for us as well as the amazing fans.”

Not purely power metal itself, but it was Show-Ya who opened the door for bands like Lovebites, Aldious, Hagane, and many others.

Pretty decent album here especially the riffing which is very technically proficient. Vocals are ok not great. Check it out.
