My list of 2017 would look something like this:
1. BLACKFIELD - Blackfield V (great album, no weak tracks, love it!)
2. LEGACY OF EMPTINESS - Over the Past (excellent discovery, great new band, excellent album)
3. DOOL - Here Now, There Then (great debut, came unexpected)
4. GOD DETHRONED - The World Ablaze (excellent 'comeback' album, might be their most consistent album of their career)
5. REBIRTH OF NEFAST - Tabernaculum (in the nick of time for 2017, made this discovery, a great Black Metal album which requires many listens to discover its treasures, I will probably listen a lot more)
6. AOSOTH - V - The Inside Scriptures (strong album, but not as captivating as its predecessor which made it to be my album of the year 2013)
Alright, but ultimately disappointing:
PARADISE LOST - Medusa (tried, but can't really get into it, just like the previous album)
ENDEZZMA - The Arcane Abyss (great debut EP and album, this sophomore album doesn't live up, although decent)
OFERMOD - Sol Nox (after the incredible Thaumiel album and good subsequent EP (Serpents' Dance), this album didn't do it for me, sadly..)
Need to listen more:
MORBID ANGEL - Kingdoms Disdained (sounds somewhat promising on first listen, but it didn't have me come back for more, blame Rebirth of Nefast for that too)
Overal 2017 was a bit luke-warm for me concerning new music. The best and most intense music I listened to this year was from earlier years. My band of the year is no doubt The Devil's Blood, what a treasure to discover.
