On this edition of StudioTulsa, we speak with Tim Sharp, the well-regarded and widely experienced Artistic Director and Conductor of the Tulsa Oratorio Chorus (or TOC). Later this week, on Thursday the 15th, the TOC will present a special holiday program, "The 'Glorias' of Christmas," beginning at 7:30pm in the Lorton Performance Center on the University of Tulsa campus. This concert will feature two separate and distinct (but equally wonderful) "Glorias" -- one by Antonio Vivaldi, the other by Francis Poulenc -- that both draw upon the same written text. Per the TOC website: "Justifiably one of Vivaldi's best-known works, 'Gloria' was only rediscovered well into the 20th century but has quickly become a worldwide seasonal favorite. It is a sumptuous and exciting choral/orchestral experience. Francis Poulenc's composition of the same 'Gloria' text pays tribute to Vivaldi's rhythms, but in an entirely different, but still exciting, tonal and rhythmic language. These two works celebrate the season with vocal fireworks and Christmas color. In this concert, TOC will be accompanied by players from the Tulsa Symphony Orchestra."
