Concrete and Grass Lowertown Music Festival runs Sept. 5-7 with a main stage in Mears Park and an indoor stage at the Black Dog.

I don’t know about you, but we’ve used up pretty much all of our vacation days at this point. St. Paul public schools are starting this week, the state fair is wrapping up for another year, and most (but not all) of the season’s big outdoor art festivals have come and gone. Still, there are a few last hurrahs remaining before we say goodbye to summer. This weekend, you’ve got three good ones to choose from.

Concrete and Grass Music Festival: This annual sampler of local live music (and Knight Arts grantee) in Lowertown’s Mears Park is one of our family’s favorite ways to wrap up the warmer months. Bring a lawn chair and let the kids run around in the grassy areas beyond the bandshell, while you listen to a range of performances Thursday, Friday and Saturday evenings. Scheduled highlights include classical fare from Saint Paul Chamber Orchestra and Minnesota Opera; singer/songwriter Lucy Michelle, with New Standards’ Chan Poling and John Munson; moody electronic pop by Halloween, Alaska and the genre-defying, classical-pop fusion of the Copper Street Brass Quintet.

Concrete and Grass Music Festival runs September 5, 6 and 7 primarily in Mears Park, 221 E. Fifth St., St. Paul. For more information and the full lineup of performances (including an auxiliary stage at Black Dog Coffee and Wine Bar), visit www.concreteandgrass.com.

Western Sculpture Park Festival: Public Art Saint Paul’s annual shindig in this small urban sculpture park is just right for families. This noon-to-five festival offers face painting, spin-art and other make-and-take activities, puppet shows, a local art exhibit tent, live music and dance performances. There are also a handful of food and drink vendors on site, and a sweet little playground right on the premises, too, to get the sillies out.

Western Sculpture Park Festival takes place from noon to 5 p.m. on Saturday, September 7 at 375 Marion Street, St. Paul.

Mixed Precipitation’s “Agent Fidelio”: This year’s picnic operetta by Mixed Precipitation has been traveling through community gardens, orchards and urban farms across the Twin Cities metro since mid-August. According to the show description, “It’s Beethoven’s opera of revolution and liberation retold with secret agents, covert operations and undercover antics.” As they watch and listen to the opera unfold in the gardens surrounding them, audiences are also treated to a five-course sampling menu, featuring dishes inspired by the opera and made with locally sourced ingredients. It’s a delight, and affordable too – suggested donations range from $10-$20 per person. Just four shows (over two weekends) remain. “Agent Fidelio” will be performed at House of Hope church (797 Summit Ave., St. Paul) at 4 p.m. on Saturday, September 7. If you can’t make the St. Paul show this Saturday, you can catch the operetta in St. Louis Park’s Bronx Park Community Garden on Sunday, September 8; there are also shows next weekend, at the Women’s Environmental Institute Farm and Orchard at Amador Hill in North Branch and in Swede Hollow Park on St. Paul’s East Side.

“Agent Fidelio” by Mixed Precipitation runs for two more weekends, with shows September 7, 8, 14 and 15. To find ticket information and specific show times, visit www.mixedprecipitation.org/shows/agent-fidelio-a-picnic-operetta.
