Audience interaction plays a huge part in Northern Spark, which runs from 9 p.m. Saturday to 5:26 a.m. Sunday.

You might become part of the show in these events, most lasting all night long:

Don't You Feel It Too?

Sea Change patio at the Guthrie Theater

Grace Minnesota, Marcus Young and a team of dancers lead the way in a participatory street dance where everyone uses their own MP3 player to unleash their inner joy. Thirty-minute workshops throughout the night begin with a brief introduction to the body-mind practice, followed by a chance to grow vulnerable yet resilient, accompanied by your favorite tunes.

The Change Booth

West River Pkwy. at Portland Av. S.

Riley Kane's and Mike Haeg's project mixes vaudeville with dystopia, featuring a cast of violinists, climate-change deniers, ventriloquists, burlesque dancers, futuristic impersonators and mimes. Each act performs for 40 minutes, throughout the night.

Bimo Gugah/ Bimo Prevails

Mill City Museum

This is one Spark performance you shouldn't miss. Sumunar Gamelan & Dance Ensembles are flying in guest artists from Indonesia and around the country for an all-night performance of Wayang kulit, a Javanese art form using shadow puppetry, music and dance. Led by Joko and Tri Sutrisno, it tells the story of Bimo Gugah, who must navigate volcanoes, earthquakes and droughts to save the world.

The Night Library

Mill Ruins Park

A hit at last year's Spark, this piece is set far in the future, long after the library has succumbed to the marsh due to severe flooding and storms. Step inside the 44-foot structure for a highly imaginative ride featuring the talents of Jon Mac Cole, Olli Johnson, David Pisa, Nico Swenson, Michael Torsch and Rhiana Yazzie, plus staff from the Hennepin County Library.

Census

West River Pkwy. between Portland Av. S. and the Guthrie

With a cast made up of dancers and movers of various experience levels and under-represented communities, "Census" invites audience to join the performance, with a goal of getting 100 people performing in a 170-yard-long space throughout the night. Employing multimedia and Pramila Vasudevan's gestural choreography drawn from storytelling practices in India, the work contemplates how communities engage with difference, and how systematic information affects us.

Water Quality Sing-Along

Mill Ruins Park (4:45 a.m.)

Interdisciplinary artists Jane D. Marsching and Andi Sutton of Plotform use water quality data taken from puddles, tap waterand other overlooked bodies of water as source material for a song scale made up of popular tunes from the past 100 years.
