The University of Tennessee Opera Theatre is taking a break this spring from the staples of the 18th and 19th Century repertoire and is instead exploring the joys and adventure of a contemporary chamber opera based on well known 19th Century literature. Their choice is an interesting one: ‘Middlemarch in Spring’, a recent work based on the George Eliot novel ‘Middlemarch’, with music by Allen Shearer and a libretto by Claudia Stevens.
