American countertenor Andrew Hallock graduated in 2002 from the University of Texas with a Bachelor of Music in Composition, where he also studied conducting, trombone, and voice. In 2009 Andrew was awarded the Bachelor’s degree in Early-Music singing from the Royal Conservatory in The Hague, having studied with Michael Chance, Peter Kooij, and Lenie van den Heuvel. His vocal repertoire ranges from the 16th to 21st century, and he performs regularly with Cappella Pratensis, Musica Fiata, and the Kölner Bach-Vereins. In addition to a busy singing schedule, he also regularly performs on both cornett and sackbut. Andrew is particularly interested in issues of historically-informed performance and historical instrument construction, and studies instrument-building with Paul Beekhuizen. He has lived in The Hague since 2004.
