St. Francis Music Center, Little Falls, is delighted to present The OK Factor in a free concert open to all on Tuesday, August 13, 7 p.m., in Sacred Heart Chapel, St. Francis Convent, Little Falls. Playful and unexpected, The OK Factor writes and performs folk-inspired music influenced by Americana and Irish fiddle styles, with an artistry that reveals their classical training. Cellist Olivia Diercks and violinist Karla Colahan put on a splendid blend of original and popular selections, ranging from Beatles tunes to Scottish jigs. The two straddle the line between jazz, pop and classical and the result is pure magic. The OK Factor will also be a part of ‘String Expedition,’ a fun-filled workshop for string students from grades 1 to 12. This workshop will take place at St. Francis Music Center the afternoon of August 13. Students who participate in the workshop will have the opportunity to perform a song with The OK Factor at the evening concert. The OK Factor will also play outside at the Shoppes of Little Falls on August 13, 11 a.m., as a pre-show to the evening’s concert. Mark your calendars now for an evening of beautiful music sure to appeal to everyone! This activity is made possible by the voters of Minnesota through a grant from the Five Wings Arts Council, thanks to a legislative appropriation from the Arts and Cultural Heritage Fund.
