Mammoth Summer Jam 2020

Welcome to The Summer Jam in Mammoth Lakes, California!

Dear People of the Jam,
We hope and pray that all are staying safe and healthy. We held out as long as we could, but it is time to face a difficult decision. Summer Jam will not be held on the June 25th weekend this year.
We have rescheduled the 2020 Summer Jam for September 25th & 26th 2020! Thinking “Reflections of Summer – Jam”? Headlining Keller Williams on Saturday September 26th. A full refund will be offered to all those who purchased tickets and cannot make the new dates.
Please follow all of the bands in this line up, and every line up we have ever hosted. You can support them in a ton of great ways by purchasing music and swagg and donating on one of their live feeds. They are all creating and doing what they love, and need our support now more than ever. #supportlivemusic
