Denver choral group Kantorei performs a concert this weekend featuring new music by its composer in residence.

Norwegian composer Kim Andre Arnesen is in Colorado this week to help Kantorei rehearse his newest pieces. He’s collaborating with the singers for the 2015-16 season.

Kantorei performs Arnesen’s music Saturday at Denver’s Montview Presbyterian Church and Sunday at Englewood’s First Plymouth Congregational Church.

The program also includes “Passion Week,” a piece by Lithuanian composer Maximilian Steinberg that was published quietly in the 1920s and rediscovered in 2014.

The range of different choral styles on this weekend’s program is impressive, Arnesen told CPR Classical's David Rutherford.

“I think I have developed as a composer in this process,” he said. “and realized I have one voice but it can be used in many different ways.”
