The old saying that opposites attract sometimes makes it difficult to perform duets.

Such is the case with Carrie Vecchione and Rolf Erdahl, who met and fell in love while attending Ball State University in Indiana. Their plans proved more problematic, however, when they decided to entwine their personal and professional lives in a place called Apple Valley, Minn.

That’s because her instrument is the oboe and his is the double bass. It’s not a combination that has attracted many composers. But nonetheless, Vecchione and Erdahl have persevered and done quite well.

And they’ve inspired a few composers along the way. One of them, Timothy Goplerud, has written a double concerto for them that receives its premiere in Duluth next Wednesday as the season-ending concert by the Lake Superior Chamber Orchestra.

The piece was commissioned by the orchestra, which in 23 seasons has earned a reputation for adventuresome programming. Goplerud’s work, titled “Rondo Buffo,” may be the first double concerto ever written for oboe and double bass. Vecchione describes it as a “vivacious, virtuosic mix of classical and jazzy styles.”

Vecchione and Erdahl have collaborated with Goplerud before, and his work is featured on their debut album, “It Takes Two.” To learn more about them, go here.

Next Wednesday’s concert takes place in the Weber Music Hall at the University of Minnesota-Duluth. The program also features Vecchione performing Lille Bror Soderlundh’s Concertino for Oboe and Strings and Rolf in Henry Eccles’ Sonata for Bass and Strings. Works by Sibelius and Mozart (Symphony No. 39) round out the program.
