I think the melodic side of Amoral is such a big part of us nowadays.
I didn’t wanna go all the way back to growling.
Niko’s vocals are more a special effect that we use when it’s necessary and brings that “extra something” to the song.
Then again Niko also came back as a guitar player... The album is obviously heavier because of Niko.
 Ari sings super clean.
There is no rock’n’roll in his sound on the new album.
 Niko does all the aggressive parts and when Ari comes in its really smooth and deep."
