Wednesday: Are you new to the art song? Or have you been a devotee since Fischer-Dieskau was in knickers? Either way, Karita Mattila is your kind of singer. The consummate Finnish soprano, whose velvety voice does anything she asks of it, returns to the Schubert Club with a captivating program for the club's 130th season opener: Berg, Brahms, Debussy, Strauss and a trio of Finns. Her 2007 visit ended with Finnish flags being waved by fans during her encore. Veteran Martin Katz is at the keyboard. You'd be mad to miss them. (7:30 p.m. Wed., Ordway Center, 5th and Washington Sts., St. Paul. $25-$60. 651-292-3268 or schubert.org.)
