This mini album is absolutely amazing. Shin Sekai gets me really pumped, and the rest of the tracks all have a similar Mad-Hatter like mood to them. I can't exactly describe it, but its super different yet stunning. Nisshoku and Yah Yah Yah are my other two favorites. I recommend this album to everyone, even ones who don't usually like j-rock (such as myself). Please listen and don't sleep on talent aka Hello Sleepwalkers !!
