Friday-Saturday: The lush Romantic melodies of Max Bruch's Violin Concerto No. 1, and the virtuosity it demands of the soloist, make it one of the German composer's most popular compositions. This week, St. Paul Chamber Orchestra associate concertmaster Ruggero Allifranchini takes on the dual role of conductor and performer. A rarely heard novelty on the program is the overture to Richard Strauss' opera "Capriccio," actually a string sextet. The concert also features musician-led performances of Rossini's "La Scala di Seta" overture and Mozart's Symphony No. 34. (8 p.m. Fri., Wayzata Community Church, 125 E. Wayzata Blvd, Wayzata; 8 p.m. Sat., St. Paul's United Church of Christ, 900 Summit Av., St. Paul. $5-$25. 651-291-1144.)
