Depending on the source, the English-language equivalent of the Brazilian slang term "matuto" appears to be "country boy" or "bumpkin" or "hillbilly." What it absolutely isn't is "critically lauded ensemble selected as American Musical Ambassadors for the U.S. State Department."

Yet that is indeed a fitting description for the capitalized Matuto, the sextet of touring musicians appearing locally as Quad City Arts' latest Visiting Artists. After a week spent conducting workshops and performing for area students, these dynamic, adventurous artists and educators will present a September 21 concert at St. Ambrose University's Galvin Fine Arts Center, where they hope to excite many more listeners with the infectious thrill of Brazilian bluegrass.

That's right: Brazilian bluegrass. Don't feel embarrassed if you've never heard of it.

When Chuck Ragan stops in Davenport later this month, his fans shouldn't miss the opportunity to see him. He's not likely to announce his retirement from touring any time soon, but he's regularly talked about the difficulties of being a touring musician and the price that families pay.

And he said in a phone interview last week that someday he will hang up his guitar to spend more time with his family. "Absolutely," he said. "I'm sure a lot of musicians would say the exact opposite. ... [But] I really look forward to that in a huge way. And I don't know when that is. ... I've always had a love/hate relationship with touring and the road. It does take a massive toll. But I think it takes more of a toll on our loved ones, who are on the other side of it."

Ragan is not, I stress, stepping out of the spotlight soon - which should be apparent from both his recent activity and his plans.

The defining characteristic of the self-titled EP from the Quad Cities band the Effie Afton is a pillowy softness - from the singing to the playing to the layer of gauze over the whole affair. Its four songs over 17 minutes are on the somnambulant side, even on the up-tempo "Great Divide" and the standout closing track, "Say Goodbye." But in a sly trick, this vibe masks a striking evolution over the course of the EP.

With its adventurous selection of 20th and 21st Century American music along with a broader sampling from the standard repertoire, the Quad City Symphony Orchestra's upcoming season represents a sharp contrast from its most recent one. Music Director and Conductor Mark Russell Smith said in a phone interview that the challenge was "finding the right balance between the familiar and unfamiliar."

He has succeeded in both selection and placement. The award-winning contemporary American music has been sprinkled among stalwart European masters, resulting in imaginatively diverse, bold programming spanning 250 years in the six Masterworks concerts.

This year, the orchestra will present works by American composers in four of the six programs and feature two world premieres of music commissioned by the Quad City Symphony organization. "This is what I like in a season," Smith explained. "Giving composers a forum for their work" and providing a "variety, and that's what the audience likes."
