Mittenfest is an annual music festival in Washtenaw County, Michigan, that serves as a fundraiser for 826michigan as well as a good-time holiday get-together. It was founded in 2006 by Brandon Zwagerman as an addition to the backyard and campus shows he had been organizing while a student at the University of Michigan – Ann Arbor.

Mittenfest is now in its 12th year, and has taken place in venues such as Corner Brewery, The Blind Pig, The Elbow Room, Woodruff’s - and now Bona Sera!

Mittenfest VII featured 60 bands over 5 packed days of music and revelry, and at least 1,500 (and perhaps upwards of 2,000) people attended over the course of the event.

The inaugural S'Mittenfest was organized as a way to provide support and promotion for the newly-founded Detroit faction of 826michigan, and featured two stages at the Magic Stick on a single summer Saturday in 2013.
