In 2011, the Oregon State Legislature declared the last week of April Oregon Dance Week. Featuring free dance classes around the state, lectures and performances, this year’s celebration will be held April 23-29.

As part of the festivities, the Oregon Ballet Theatre company will debut its new spring program, “Chromatic Quartet.” Featuring two company premieres and a world premiere, the show will run April 19-28 at the Newmark Theatre in Portland.

According to a news release, the “‘Chromatic Quartet’ celebrates surprising intersections that make for inspired partnership.” The program includes “Stravinsky Violin Concerto” by George Balanchine, “Liturgy” by Christopher Wheeldon, “The Lost Dance” by Matjash Mrozewski and “Lambarena” by Val Caniparoli.

Balanchine choreographed the “Violin Concerto” as part of the Stravinsky Festival in 1972. A frequent collaborator with Stravinsky, Balanchine wrote the piece as a “love letter to his mentor and creative partner,” according to the release. It was considered “the undisputed masterpiece of the festival.”

Wheeldon’s “Liturgy” uses composer Arvo Part’s “Fratres for Violin, Strings and Percussion.” Following “There Where She Loved” and “Rush,” “Liturgy” is Wheeldon’s third work to enter the Oregon Ballet Theatre repertoire.

Mrozewski is a Canadian choreographer on the rise. The Oregon Ballet Theatre will present “The Lost Dance” on stage for the first time. Known for his “risky and diverse repertoire” and “invigorating, witty and exciting ‘flash mobs,’” Mrozewski’s new work features electronic music by Owen Belton and costumes by Portland designer Adam Arnold, according to the release.

The program is rounded out with the return of Caniparoli’s “Lambarena.” Set to the cantatas of Johann Sebastian Bach and West African chants and rhythms, “Lambarena” blends “traditional West African dance movements with classical ballet.”
