Rock on the Range, O.A.R. and the Columbus Symphony Orchestra highlight this week's slate of five fab shows.

For years, my crack staff (pretty much me) did serious investigative journalism (a cursory Google search) to try and figure out which area of Columbus, or, more specifically, MAPFRE Stadium, is considered "the Range." The good news is it doesn't really matter. Hard-rock fans and metalheads have come to embrace Rock on the Range, the annual late-spring three-day festival, which marks its 10th incarnation this year – it's again sold out all three days.Suffice to say, if you can hear it, you're within range.

So here are five other things to keep you busy this week.

To close its 2015-2016 season, the Columbus Symphony Orchestra challenges the Euro-centric perception of classical music with three pieces by Argentine composers in "Latin Fiesta."

Tango master Astor Piazzolla's four violin concertos in "The Four Seasons of Buenos Aires" join contemporary composer Osvaldo Golijov's "Last Round" and the vanguard Alberto Ginastera's "Variaciones concertantes" to make up the program. It's a collection of brilliant showpieces for the full orchestra and some of its individual musicians.

Music director Rossen Milanov conducts; soloist Bella Hristova joins for the Piazolla.

Concerts will be held Friday and Saturday, May 20-21, at the Southern Theatre. Tickets start at $10.

This year marks the 10th anniversary of the Memorial Tournament-sponsored concert benefitting Nationwide Children's Hospital at Express Live.

We love our anniversaries, and this one is especially cool, blending three important Columbus entities -- actually, four, if you include the Jack Nicklaus Children's Health Care Foundation.

Proceeds benefit the Neonatal Intensive Care Unit at Nationwide Children's Hospital.

Oh yeah, the concert. This year's featured artists are once-local-now-international-stars O.A.R. and '90s hitmakers Rusted Root.

The concert is set for Friday, May 20 at Express Live. Tickets are $35 for general (lawn) admission. VIP tickets are available.

Columbus community leader and author Linda Kass and dynamic local chamber ensemble Carpe Diem String Quartet have combined to create a special program of music related to Kass' new novel, "Tasa's Song."

In each of three programs Friday-Sunday, May 20-22, at Worthington's McConnell Arts Center, Kass will read from the book, which tells the story of a young Jewish violin prodigy growing up in eastern Poland during World War II, and Carpe Diem will perform selections referenced in the novel, including works by Paganini, Smetana and Tchaikovsky. It's a masterful mixture of literature and classical music.

Tickets are $30 for adults, $25 for seniors and $10 for students.

British prog-psych rock outfit Purson embraces elements of metal and dark-folk, giving rise to tunes (and an accompanying live show) most theatrical. Led by frontwoman Rosalie Cunningham, the quintet boasts a decidedly modern-Medieval flair.

On the road in support of "Desire's Magic Theatre," released earlier this year, Purson will play Ace of Cups on Sunday, May 22. Philadelphia's Ruby the Hatchet and Columbus' Cosmic Moon open.

Tickets are $10 in advance, $12 day of show.

Post-punk troubadour Peter Case made his name with The Nerves and The Plimsouls (you likely recall "A Million Miles Away"). Case continues to ply his trade as a solo artist that now features double-digit records and a pair of Grammy Award nominations.

He's an Americana-with-an-edge storyteller, chronicling the human condition through well-crafted tunes and catchy hooks.

Case will play Natalie's Coal-Fired Pizza on Wednesday, May 25. Tickets are $20 reserved, $15 general admission.
