CATHEDRAL CENTENNIAL

Thursday: More than three years of work were involved in the total rebuild of the Aeolian-Skinner organ at the Cathedral of St. Paul, with pipework shipped to Warrensburg, Mo., for voicing, and new casings carved by master craftspeople in San Francisco. The results are magnificent, and the new instrument, with its four keyboards and nearly 6,000 individual pipes, will be unleashed on Thursday by the young Wisconsin-based organist Donald VerKuilen as part of the cathedral's ongoing centennial celebration. He'll play Charles-Marie Widor's Fourth Symphony, with pieces by Saint-Saƫns, Bach and Peeters, in a free program guaranteed to set the lion roaring. (7:30 p.m. Thu., Aug. 20, Cathedral of St. Paul, 239 Selby Av., St. Paul. Free.)
