Yonder Mountain String band

Colorado’s Yonder Mountain String Band pays equal respect to bluegrass traditionalists like Bill Monroe and innovators such as Bela Fleck. The band’s epic stage shows are so revered that the Yonder crew launched a “Phantasy Tour” Web site where obsessed fans can place bets on which songs will be performed and in what order (just like fantasy football, but played on a different type of grass). Anybody want to match our $5 on “In the Woods with the Munchies?” The group appears 8 p.m. today at Liberty Hall, 642 Mass.

Frank Lee

A passion for traditional songs and tunes from the rural South has fueled Frank Lee’s love of performing for the past 25 years. As a founding member of The Freight Hoppers, he presents a range of old-time music that spans Mississippi delta blues to hillbilly music from the 1920s. Lee and special guest Andrea Earley play 7:30 p.m. Saturday at Unity Church, Ninth and Madeline streets.

Heiruspecs

Heiruspecs’ live hip-hop casts a net that encompasses everything from The Roots and DJ Shadow to Run D.M.C. and Digable Planets. The St. Paul-bred group of high school friends has backed up Atmosphere, Oddjobs, Sage Francis and is currently touring in support of its latest album, “A Tiger Dancing.” Recently signed to Razor and Tie Records and soon to be supporting tours for Cake and The Walkmen, Heiruspecs’ music crosses genre boundaries and promises a unique, high-energy experience. The band joins Adara, Kelpie and DJ Cruz 8 p.m. Sunday at The Granada, 1020 Mass.

Marty Olson

Lawrence artist Marty Olson describes his work as a search for spiritual voice through color, gesture and abstracted calligraphic mark making. “I continue to search for the perfect gesture,” he says. New works by Olson in paint and mixed media — along with a few previously shown pieces — will be on view through March 5 in a solo exhibition at Unity Gallery, 900 Madeline. An opening reception for the show will be from 5 p.m. to 7 p.m. Saturday.

Mozart set his opera “Cosi fan Tutte” — which premiered in 1789 — in late-18th-century Italy. But when KU Opera debuts its production of “Cosi,” powdered wigs and leotards will be conspicuously absent. That’s because KU Opera’s version will be set in 1950s Lawrence. The show tells the story of a philosopher, Don Alfonso, who makes a bet with two young soldiers that their girlfriends will be unfaithful to them while they’re away at war. The show opens at 7:30 p.m. today at the Robert Baustian Theatre, Murphy Hall.
