This program charts a compelling lineage for wind ensemble: Crusell’s Introduction, Theme and Variations blossoms with classical poise and urbane charm, likely shaped for Linköping’s historic band tradition—an elegant conversation between clarinet and warm-grained winds. Mats Larsson’s Concerto for Trombone and Wind Instruments treats the soloist as a wordless singer moving through a sequence of “rooms,” where lyrical arches and surging climaxes alternate with flashes of burlesque; most often, a tender, melancholy Romantic hue prevails. Nils Tykesson’s Three Arabesques distils the textures of a lakeside landscape into patterned sound: Fibonacci traces, golden-section spans and Escher-like reflections yield mosaics that swing between softness and steel, woodwind filigree and brazen resonance. Peter Bengtson’s Hekas!—its title nodding to an Eleusinian processional call—drives forward with ceremonial energy yet resists narrative, a concentrated, six-minute blaze of color and rhythm. Threaded through is the ensemble’s long habit of commissioning and renewal, a modern counterpart to the Crusell era that gives these works both historical ballast and freshly minted immediacy.
