KATHRYN MUELLER (soprano) has been described by the Albuquerque Journal as a young singer "who thoroughly captures the imagination," and has also been praised by San Francisco Classical Voice for her "lovely tone and easy agility" and by the Miami Herald for her "charm [and] dizzying flights of coloratura." Her frequent solo concert engagements across the United States include appearances with American Bach Soloists, the Washington Bach Consort, Santa Fe Pro Musica, Phoenix Symphony, Winston-Salem Symphony, Tucson Symphony Orchestra, Miami's Firebird Orchestra, Atlanta's New Trinity Baroque, and Chicago's Ars Antigua. Ms. Mueller has also sung the operatic roles of Amy in Little Women, Monica in The Medium, Belinda in Dido and Aeneas, and Miss Pinkerton in The Old Maid and the Thief with companies including Arizona Opera and Bach Collegium San Diego. She recorded two GRAMMY-nominated albums with Seraphic Fire, and is featured as a soloist on recordings by New Trinity Baroque, the Santa Fe Desert Chorale, Tucson Chamber Artists, and Seraphic Fire, including Seraphic Fire's best-selling Monteverdi Vespers of 1610. In 2011 Ms. Mueller was one of four fellows in the prestigious Adams Vocal Master Class at the Carmel Bach Festival. She was also a finalist in the 2012 New York Oratorio Society Solo Competition. This fall her soprano duo Les Sirènes will compete in the finals performance of Early Music America's Baroque Performance Competition, and will give featured concerts on the San Francisco Early Music Society, Phoenix Early Music Society, and Arizona Early Music Society series. Other upcoming performances include Kathryn's debut with the Portland Baroque Orchestra, and repeat engagements with American Bach Soloists, Santa Fe Pro Musica, Seraphic Fire, and Albuquerque Baroque Players.
