About this event

 
This summer, Mass N Tha Grass returns to Sinking Valley Fairgrounds in Altoona, PA for our 7th annual festival!

This event will feature a modern mix of music of all genres! This isn't just your typical jam band festival - we are non-discriminatory when it comes to the musical artists we host, and are trying to break down the boundaries that sometimes exist between listeners of different types of music. It's not just a random hodgepodge - it is by design.

MNTG 2026 is a 3-day camping festival which will host 40+ art/craft/food vendors, 50+ unique musical performances from some of the latest bands currently creating original music, wooded/field camping areas (tents/RVs/car camping permitted), fire/flow performances, live art, games, workshops, & more! We are hoping to open up a brand new stage area, which will give us 3 covered sound stages, one of them being an indoor stage.

Come have a great weekend with us in August of 2026! Help this event grow and add new additions by inviting your friends and family to this event page. If you are interested in becoming an event sponsor to make sure this festival can continue annually, send us an email @ massnthagrass2023@gmail.com
Thank you for supporting Mass N Tha Grass Music & Arts Festival 🙏 We truly appreciate it!
