[AROI] A few years ago, we first performed together, and we were amazed by the comfort, the freedom of development, and the depth and joy of music that creates a completely different scene every time. This improvisation trio was born... Yuji Ishihara, Junji Mori, and Yuki Saga. This time, we took on the name of the unit. The treasure box of the sound of the three is becoming more and more fulfilling.
