If there was ever an under-rated I think it is ヤなことそっとミュート(Yanakoto Sotto Mute). They have some of the most powerful songs out there. The music and sound of the lyrics really strike me as full of emotion. I can just listen to them all day long. I was really excited when I woke up today to this announcement.
A new single, I am super excited. Now, they are releasing it in two forms. First, on July 26th it will come out on iTunes, most likely in Japan only. For a person that prefers physical media, like myself, it will be a tiny wait. The CD goes on sale August 16th. Of course I am sure the wait will be worth it, they always have super album art to look at while you listen to the CD.
It is named 「STAMP EP」and will cost ¥1080 (w/ tax) other details have not been announced yet. I believe this is the album art.
Now if you missed it they included a video announcement in their tweet.
