Week's best classical concerts: SPCO's baroque feast, new a cappella work by Caroline Shaw

Lou Harrison was born 100 years ago in Portland, Ore., and he's one of the great originals of 20th-century music. He incorporated world music into the classical mainstream. And he was particularly influenced by the Balinese gamelan, at one point developing an American equivalent built of tin cans, empty oxygen tanks and bits of aluminum. Harrison's legacy is celebrated by St. Paul contemporary music group Zeitgeist in a fascinating mini-festival of four concerts featuring his chamber pieces, works for gamelan and vocal music. (7:30 p.m. Thu., Fri., Sat.; 2 p.m. Sun.; Studio Z, St. Paul; $10-$15, ­zeitgeistnewmusic.org)

Celius Dougherty was born in 1902 in Glenwood, Minn., and composed 200 songs over the course of a lengthy career. Pianist Mark Bilyeu and mezzo-soprano Clara Osowski showcase some of Dougherty's work with a recital featuring recordings, manuscripts and letters from local collections. (7:30 p.m. Thu.; Schubert Club Museum, Landmark Center, St. Paul; $12, 651-292-3268, schubert.org)

Jeannette Sorrell, founder of Cleveland's Apollo's Fire (one of America's best baroque ensembles), is in town for a special program with the St. Paul Chamber Orchestra this week. The concert includes works by Handel and Rameau as well as SPCO soloists playing Bach's Double Violin Concerto and Vivaldi's Concerto in G Minor for Two Cellos. Bonus: Sorrell leads her own arrangement of Vivaldi's "La Folia." And Bach's Orchestral Suite No. 1 rounds out this feast of baroque music-making. (7:30 p.m. Thu., Temple Israel, Mpls.; 8 p.m. Fri., Wayzata Community Church, Wayzata; 8 p.m. Sat., St. Paul's United Church of Christ, St. Paul; 2 p.m. Sun., Benson Great Hall, Bethel University, Arden Hills; $13-$43, 651-291-1144, thespco.org)

MacPhail Center for Music examines the intermingling of Eastern European and Jewish folk music with the latest installment of its Spotlight Series. Peter Ostroushko plays Ukrainian folk music on his mandolin. The school's faculty musicians perform Paul Schoenfield's Klezmer-inspired "Trio" and David Evan Thomas' "Fantasy on a Yiddish Song." And the Minneapolis theater troupe Impossible Salt throws its weight behind Brahms' "Hungarian Dances." (8 p.m. Sat., MacPhail Center for Music, Mpls.; $15-$25, 612-767-5250, macphail.org)

Tuvan throat singing, yodeling and Sardinian cantu a tenore are just a few of the vocal styles studied by the eclectic Roomful of Teeth ensemble. The vocal group is joined by experimental pop musician Nick Zammuto (most famously of the Books) for the Minnesota premiere of Caroline Shaw's Pulitzer Prize-winning a cappella composition "Partita for 8 Voices." A co-presentation from the Schubert Club, Walker Art Center and SPCO Liquid Music Series, the concert also features a world premiere by Zammuto. (7:30 p.m., Wed.; Aria, Mpls.; $31, 651-292-3268, schubert.org)
