HOOD RIVER — Combined performances by the Gorge Sinfonietta and the Voci Community choir are always an event. On April 17-19, the two ensembles will come together for a performance called “Roads Not Taken.”

The title comes from a line by Robert Frost, whose poetry is featured in “Frostiana,” a beloved setting of Frost’s poems for choir and orchestra. The 75-voice Voci Choir will be accompanied by a chamber orchestra conducted by director Dan Kenealy. Composed by Randall Thompson in 1959, the composer’s simple and appealing music reflects Frost’s plain but profound choice of words.
