Žak’s performing career is heavily fueled by his musicological and performance-based research. Whether his focus in on the influence of the transatlantic slave trade on the history of Western music, music for the English theatre, or Italian lute music, among other topics, his goal is to make a real contribution to the state of human knowledge, and then to turn that knowledge into superb and compelling musical performances. Most of Žak’s and L’Avventura’s concert programmes are based on his original research, performing editions, and musical arrangements, and regularly revive forgotten musical works and neglected historical performance practices.
Žak's writings on historical performance practice have been translated into French, German, Spanish, and Korean, and appear in some of the leading journals and magazines in the field. His current projects for publication include an edition of eighteenth-century lute concerti for
A-R Editions, as well as an upcoming performing edition (with Vanessa L. Rogers and Berta Joncus) of Isaac Bickerstaffe's 1762 opera Love in a Village, to be published by Bärenreiter in 2019. Further, he frequently presents his research at conferences in Europe and North America and speaks on various related topics on BBC Radio 3 and American NPR. 2019 will also see his first TEDx Talk. Recent conference presentations include those at the Annual Meetings of the American Musicological Society in San Antonio and Philadelphia; the 16th Biennial International Conference on Baroque Music in Salzburg; the SECEM, the
Universidade Nova de Lisboa; the Handel, Purcell, and Literature conference at Senate House, University of London; and the British Society for Eighteenth-Century Studies.
In addition to his busy performing schedule, Žak holds a Visiting Professorship at Rhodes College in Memphis, TN, where he teaches classes in Creative Entrepreneurship, Music History, and Great Books, and a Visiting Fellowship at Goldsmiths, University of London, teaching classes that combine performance and scholarship. Before that, Žak was the Director of Early Music at the University of Hull. He has also been active as a lecturer in historical performance practice, collegium director, and lute teacher for various early music societies and at the University of Oxford, Royal College of Music in London, USC Thornton School of Music in Los Angeles, and the University of California at Fullerton. As an extension of his educational activities, in 2011 Žak formed the London Community Baroque Orchestra (now functioning as an educational arm of L'Avventura London) based at the Foundling Museum in London, which he also directs. The goal of the organization is to provide training in historical performance practice to its members and to present high-level musical performances. Žak has been a recipient of various prestigious awards, prizes, and scholarships including a Society for Theatre Research award for reconstructing and recording music from English ballad operas and the Dowland Prize for Lute at the John Kerr Competition in Kent.
