Memories of a cave in ancient times, played by stone. This is the second collaboration work by Takahiro Kido and Yuki Murata, music composers who also are active as members of Anoice, RiLF, and Films, together with Kenji Azuma, an ambient music artist who plays a range of unusual instruments and the trio's first EP. It's been only three months since the previous collaboration single 'Ice Mermaid' with the basis of the song's sounds created from materials which are related to ice and water. This time, they will release the four songs-included EP 'Memories of the Stone' featuring the sounds of a stone and limestone cave. Just like their previous work, this song is also based on an illustration painted by MATSURICA who also takes charge of the artwork for some of the releases from Anoice, Yuki Murata, and Films, and it is under the theme of the exploration into a cave. A wolf finds a cave in the forest and gingerly goes into it, and steps forward to the deep as if being invited by the sounds of water dropped on the puddle and bats singing. And then, he leaves his body to energetic dance of the ancient animals drawn on the wall... Like the previous collaboration 'Ice Mermaid', each artist took charge of playing various instruments, but the most notable point in this EP 'Memories of the Stone' is that they mined Sanukitoids, a variety of high-Mg granitoid found in limited area of Japan and recorded its sound in the forest. You should be able to feel the memories of the long and epic history via the beautiful and clear sound of the stone which has existed since ancient times. Step into an adventure with the main character wolf, Rem, while looking at the illustration.
