The Oregon Symphony’s first artist-in-residence, cellist Alban Gerhardt, arrived in Portland this week and is already making himself visible around the city. Yesterday afternoon, he worked with members of the Portland Youth Philharmonic in a three-hour masterclass. Today (Oct. 26 – 4:00-5:00 pm) he’ll take the Bach cello suites to Pioneer Place Mall for a one-man flash mob (he’ll be in the area by the escalators in the atrium). There are more visits and performances planned through the weekend – visit the special OSO site here.
