Input: Question: How many years has the festival that hosted the reinterpretation of Handel's Messiah been going on? Passage:Among his works are The High Mass, a Requiem, concertos for flute, guitar, piano, and cello, and the 2001 opera, on a libretto and originally directed by Claes Fellbom, who commissioned the work for the centennial of the Swedish opera company. Fellbom translated the opera into English and directed its first production in that language at Indiana University in February 2003. In 2006, Sandstrom's Ordet - en passion was performed on 24 March in Stockholm. A number of his works were inspired by significant choral works by Bach and other composers, but reinterpreted in Sandstrom's very personal style. These include a set of the six Bach cantata texts in Bach's structure (double choir plus four-part chorale), a reinterpretation of the text of Handel's Messiah commissioned and premiered by the Oregon Bach Festival in 2009 and also performed at the Rheingau Musik Festival that year, and works by Purcell.
