The whole album is really solid from start to finish! All of the songs are written really well in a way that keeps them interesting at all time! And most of the songs have this "dark" atmosphere to them that works really well for me!
The band is crazy talented with Shiren's face melting shred on the lead guitar, Nanami's solid bass lines, Gight's excellent drum work, Yui's beautiful vocals and lyrics and Takaha's amazing song composing skills, rythm guitar and harmony parts!
In conclusion I think this is personally one of my favorite albums ever, and I recommend you listen to it!
l like the sound. The lead singer has a very cute voice, but it's contrasted by a very bombastic band. She's also very skilled as a singer; probably helps that she's also an actress in a few animes. I would say this would be good for fans of Anette-era Nightwish
