(Arlene Schnitzer Concert Hall, 1037 SW Broadway) While I’m not advocating the Oregon Symphony jacks up its ticket prices, the first half of tonight’s program is worth the goddamned cost of admission all by itself. Norwegian composer Edvard Grieg gets the party going with the Suite No. 1 from Peer Gynt, which contains both of his biggest hits. I’m hoping my impulse control is strong enough to resist bitch-slapping fellow concertgoers who will inevitably hum along with these magnificently infectious tunes. After their visit to the Hall of the Mountain King, those in the supremely lucky Schnitzer crowd shall witness nothing less than the most influential classical violinist currently residing on our planet: Hilary Hahn. She’s sitting in for three glorious days with Rip City’s biggest unplugged band, to bring another Scandinavian composition to life: a fiddle concerto penned in 1911 by Denmark’s favorite musical son, Carl Nielsen. The work’s enigmatic emotional flare and sweet-ass solo turns will dazzle with fresh intensity in the hands of this thirtysomething virtuoso. Hahn’s appeal is so universal her fucking violin case has amassed 25.4K followers on Twitter, so prepare to have your tiny, weed-encrusted minds blown when you catch the owner of this luggage in the flesh. You’ll need an intermission to recover. ANGRY SYMPHONY GUY
