This is a good discover for me. Noisy and dirty reccording with a lot of repetitions, but also a lot of underused effects. The constructions of the songs are very different from the other bands for most of the songs. Their is also catchy songs such as "ダンボールの家" wich is my personal favourite of the cd (I love when the music stop for a second). The cover is also very nice. It probably refer to the title song "大きく開く" which means "open wide". We sadly can't understand all the lyrics because of the effects on the voice.So finally, I think their next releases will be awesome if they got more money to do it!By the way, their is an uncredited intrument on "ゼアウィルビーブラッド". I think it's a string instrument with a lot of distortion on it. If someone have information about it, please tell it!
