Music Festival Master / Editor-in-ChiefKeisuke Hane
Editor-in-chief of RAG MUSIC and in charge of music festivals. When I attended my first music festival as a freshman in college, I was captivated by its charm—“I can’t believe there’s a place this free and this fun.” I share information about wonderful music festivals every day to help grow the community of festival fans.

I’ve put together a list of music events happening in September, including outdoor rock festivals, circuit-type festivals, and jazz street events.

Grateful for the chance to encounter amazing music again this year!
