It may take place under the St. Paul Chamber Orchestra's umbrella, but the adventure-minded Liquid Music series is all about stepping outside the safe zone of classical music. The 2016-17 season announced Tuesday promises some risky business by artists who normally rock the concert stage.

The moody, rhythm-driven Twin Cities pop band Poliça and TV on the Radio frontman Tunde Adebimpe are involved in two of the four world premieres to be featured next season.

Another concert will spotlight saxophonist Colin Stetson, a frequent collaborator with Bon Iver and Arcade Fire, who'll open the season Sept. 30 at Walker Art Center (a co-presenter) with "Sorrow," billed as a reimagining of Henryk Górecki's pathfinding 3rd Symphony.

Poliça follows Nov. 18 at the Fitzgerald Theater with a new work developed in collaboration with Berlin ensemble stargaze. "Music for the Long Emergency" was inspired by a book that predicts the collapse of industrial society.

"It's time for us to stretch ourselves out of the path that we've been on for a while, and be challenged by new people," Poliça frontwoman Channy Leaneagh says in a video on the project's Indiegogo crowdfunding site.

The season closes May 18-20, 2017, with Adebimpe's "A Warm Weather Ghost," another copresentation at the Walker. A stage piece that includes visual art by the singer, it's described as a surreal work "conceived as a hero's narrative pushed through a psychedelic fever dream."

Other premieres will come from jazz trumpet phenom Ambrose Akinmusire – who was featured on Kendrick Lamar's Grammy-winning album "To Pimp a Butterfly" – and vocal ensemble Roomful of Teeth, working with aural collagist Nick Zammuto.

Liquid Music also will lay the groundwork for what promises to be an exciting event in 2017-18, as the genre-mashing flutist Nathalie Joachim begins a "virtual residency" to develop a project exploring Haitian song and the role of women's voices in Haitian music.

Tickets are on sale for the full season as well as individual concerts. See the Liquid Music site for details on these shows:
