I am most keen on the new Kreator and Sepultura albums at least for the first month or so of 2017. Kreator hasn't put anything out since 2012 and its gonna take quite a feat to surpass Phantom Antichrist.
I can still hope.
Just like, even though Insomnium put out out an album in 2016, it was a 40 minute concept, so I'm hoping the next album won't be more than 2 years after that. I figure they have more stuff written that wasn't a part of the concept.
For me, the Edenbridge and Xandria albums are must-haves.
Dunno if you've picked up or ordered the new Xandria album yet? If not, make sure you get the 2-CD mediabook. The acoustic bonus CD is a must-have!
