“Dr. Seuss’ The Sneetches,” Children Theatre’s adaptation of Seuss’ segregation-era story about creatures with and without stars on their bellies, is quite resonant. The production has standout performances by Natalie Tran, Kim Kivens, Reed Sigmund and Bradley Greenwald as magnetic con man Sylvester McMonkey McBean. Altogether, they make this show a fun and pun-filled parable for our times.


Ends March 26. Children’s Theatre, Mpls., $15-$71, childrenstheatre.org

After big-name fans including David Byrne and Kurt Cobain discovered Os Mutantes’ collectible 1966-1974 albums, this psychedelic tropicalia garage-rock band from Brazil re-formed in the mid-2000s and has been going strong ever since under original co-leader Sérgio Dias. Their first U.S. tour in four years promotes a wild new album, “Fool Metal Jacket,” and includes the opening party for the Art Institute of Chicago’s “Hélio Oiticica” exhibit after Minneapolis.

The movie “Hidden Figures” has captivated the country, drawing big audiences and earning an Oscar nomination for best picture. But, you know, the book came first.

Shetterly will discuss her books with Michele Norris.


6 p.m. Tue. Northrop auditorium, Mpls., free but tickets required.



Hugh Wolff’s name may be familiar to many classical concertgoers in the area. He served as principal conductor and later music director of the St. Paul Chamber Orchestra in the late ’80s and ’90s, leading many notable recordings.

Soulful singer Valerie June made a splash with her 2013 disc, “Pushin’ Against a Stone,” produced by Dan Auerbach. On record and in concert, she established herself as an idiosyncratic but irresistible music maker of various styles of American music, from Appalachian to gospel. On March 10, she’ll drop the follow-up album, “The Order of Time,” which is sparser in sound but the lead single, “Shakedown,” is a head-bopping, foot-stomping blues rocker.


7:30 p.m. Wed. Cedar Cultural Center, Mpls., sold out, thecedar.org

Composer John King, who grew up in Minnesota, first got John Cage’s attention in the early 1980s by sending him music made with fishing tackle. That led to a close relationship with the Merce Cunningham Dance Company and a front-row seat to musical history. This month, King curates “Music for Merce,” a two-night performance featuring longtime collaborator David Behrman, composer Christian Wolff and Radiohead drummer Philip Selway.
