I have listened to the new album about 5 times now, and I think it will end up being even more polarizing than Unia. The new album demands much more patience and repeated listenings than their previous offerings. Even Unia had more variety and several catchy songs that you could love immediately, like Paid in Full and It Won't Fade. I wasn't surprised to look online and see that a huge majority of The Days of Grays reviews were negative.
"The Last Amazing Grays" is one of the best songs they have ever done and I hope it will be a crowd favorite at live shows. "Zeroes" is so much fun and reminds me of Edguy. "The Dead Skin" contains the heaviest moments on the album and some of Tony's best screams! And I think the "Everything Fades to Gray" tracks are both pleasant and interesting.
"Juliet" has such an awesome intro and hopefully I'll eventually like the rest of the song too. "Breathing" is a decent song but I'm not sure it's on the level of Sonata's other gorgeous, somewhat melancholy tracks like Last Drop Falls, Under Your Tree, Good Enough is Good Enough, and Draw Me. The other ballad on the album, "As if the World Wasn't Ending" is doing absolutely nothing for me.
I loved Unia and both of the new tracks on their Myspace profile (Last Amazing Grays and Flag in the Ground) so maybe my hopes were impossibly high. This album will definitely be a grower, but I'm much more optimistic than I was after my first listen, where I was practically in a state of shock of how indifferent I was.
