Symphony Active NEETs is a Japan live doujin orchestra circle. In 2014, they started their activities as a sister circle of Tokyo Active NEETs. Red Meteor, who had wanted to create orchestral works for a long time, and Nando Meko, who was his disciple at the time, hit it off and formed the group. Indo Nameko is in charge of the arrangement, and Red Meteor is in charge of the overall production and video production.

At the beginning of its formation, it was a type of work, but in order to break through the preconceived notions of the conventional doujin orchestra, they decided to record live performances outside of profitability. The arrangement of the indon lick and the video and production of the red meteor were hooked, and it was established as a one-of-a-kind live orchestra circle.
