Boise’s hometown favorite Treefort Music Fest was postponed due to the coronavirus pandemic in March 2020. However, Treefort organizers are working to bounce back and prepare for the festival’s return in September 2021.
Treefort 9 had originally been planned to happen in a pre-pandemic world last March, but the dates have since moved to Sept. 22-26, 2021.
With the recent spike in the Delta variant, the Treefort team has updated and improved their health and safety guidelines for both attendees and performers who are planning on participating in Treefort 9.
On Aug. 11, 2021, Treefort published a press release containing the new guidelines for vaccination requirements.
“Anyone attending Treefort Music Fest will be required to show proof of negative COVID-19 test result or vaccination prior to entry to all official Treefort venues and programming tracks,”the press release stated. “In addition, Treefort asks that all attendees have a mask handy at all times, as some Treefort events or areas may be mask-only at certain times.”
This new requirement is encouraged for all artists, staff, vendors, volunteers and attendees who are aged 12 and older.
Before collecting concert passes, attendees must check into the TMF Pre-Check Party Zone for security screening, where they will receive an entry wristband for the performance venues.
“Free vaccines are available now and during the festival at The Egyptian Theatre
11 a.m.-3 p.m. MT, Monday through Friday,” the email read. “Vaccines may also be available on site at the festival.”
Treefort intends to resume its normal schedule immediately, with Treefort 10 taking place in the spring of 2022 — which means two festivals in just about six months.
The new addition of sanitization schedules and vaccination record requirements will help ensure performers, volunteers and attendees remain safe and healthy throughout the return of Treefort 9.

As of June 17, Treefort has announced that 50 more artists will be joining this year’s festival. Fan favorites such as Japanese Breakfast, Goth Babe, Tennis and The Marías are among the 417 artists performing at Treefort 9.
“This unique September version of Treefort is shaping up to be one of our best yet and we are looking forward to bringing the Treefort family back together to share and discover great music,” Treefort Festival Director Eric Gilbert said.
Many artists from the original March 2020 lineup will be carried over into September 2021 for the festival’s return. The event schedule has also been updated for attendees who are looking to organize their Treefort 9 experience.
“The enthusiasm from our community about a September edition of Treefort has been reassuring and the excitement from artists has been really motivating,” Gilbert said. “We’re looking forward to gathering again safely and celebrating live music, art and community after a long, quiet year.”
“Community Owner” tickets, previously known as “Early Bird” tickets, went on sale on April 8, 2021.
All other Treefort tickets — though limited — are now available, including the $250 “Discovery,” the $420 fast pass “Zipline” and the $150 “U21” for audience members below the age of 21.
Single-day passes are available for purchase as of July 30.
