Whiplash Weekend: Bass Music Friday, Front-Porch Sunday at KettleHouse
Here is your assignment for the next three days, should you accept it: get your heart rate up on Friday and let it come all the way back down by Sunday. The KettleHouse Amphitheater calendar has engineered a perfect summer whiplash weekend, and both ends are worth the drive out to Bonner.
Friday, July 17 — Tape B x Levity. This is the loud one. Tape B and Levity headline a co-billed night of modern bass music, and if you've never watched electronic production land in an outdoor amphitheater on a river, understand that KettleHouse's 4,250-capacity bowl was practically built for sub-bass. The canyon holds low end the way a good pint glass holds a head. Dress to move; this is not a lawn-chair show.
Sunday, July 19 — The Avett Brothers. And now the exhale. Two days after the bass rigs pack out, the Avett Brothers bring banjo, cello, and the kind of harmony-drenched catharsis that turns a river-bank crowd into a choir. The Avetts have spent twenty years perfecting the trick of making an arena feel like a living room; a 4,250-cap amphitheater with the Blackfoot running behind the stage is going to feel downright intimate. Bring the layer — canyon nights cool off fast once the sun clears the ridge — and bring someone you don't mind crying next to.
Why program a weekend this way? Because it's a flex, honestly. A room that can host a bass-music blowout and a folk-rock catharsis inside 48 hours is a room with range, and this is the summer KettleHouse is showing all of it. Both bills are confirmed on the venue's 2026 calendar, cross-listed across Logjam Presents and local coverage.
A few logistics, because the canyon punishes the unprepared. It's roughly a 20-minute drive from downtown Missoula out toward Bonner; leave early, because the two-lane road backs up before big shows. KettleHouse Brewery is right there. And the amphitheater's weather is genuinely mountain weather — sun-warm at doors, sweater-cold by the encore.
The move, if you can swing it, is to do both. Go feral on Friday, go tender on Sunday, and let the same patch of riverbank hold two completely different versions of you. That's not a weekend. That's a personality test with a view of the water.
