Choral music fans know all about the St. Olaf Choir, which tours around the world, is featured on PBS and has put out scores of albums since its founding in 1912. Not bad for a student ensemble from a Lutheran liberal arts college in southern Minnesota. The choir, conducted by Anton Armstrong, pictured here, is on a 14-city Southeastern tour that brings it to St. Petersburg this weekend. The a cappella program is impressively wide-ranging, from traditional works by Brahms, Mendelssohn and Purcell to Penderecki's Agnus Dei to Rosephanye Powell's Sorida (A Zimbabwe Greeting). There are sections devoted to the music of Eric Whitacre and to spirituals, including Jester Hairston's arrangement of Mary's Little Boy Child. The concert is at 7:30 p.m. Friday at First Presbyterian Church, 701 Beach Drive. $15, $25. (727) 822-2031. Tickets are sold at the door or at universitytickets.com.
