The new Hello Sleepwalkers release is Planless Perfection, which they rolled out back in March, and the VR style 360 degree song posted first is from that album. I recommend putting on your VR headset and best set of headphones for that one; being surrounded by the band while they play is quite a nice effect. The second track here, called something like the collapse of the Myth of Huai, is also from their latest realease. They are probably best known for doing the OP for the first season of the anime Noragami, which is a fun little show about an unemployed god; that track was on their 2014 album. Finally, again from Planless Perfection, a slight change of pace with their song Breaking Dawn.
