Described by Westdeutsche Allgemeine Zeitung as 'a brilliant, absolutely world-class player' he has appeared as a soloist in many international venues, including London's major concert halls and New York's Lincoln Center and Carnegie Hall. His recent discography includes two volumes of sonatas by Lefèvre in their original scoring for C clarinet and cello. Colin has published widely, especially for Cambridge University Press.

Robin Stowell is Professor of Music and Director of the Centre for Research into Historically Informed Performance at Cardiff University. Educated at the University of Cambridge and the Royal Academy of Music, he is also a violinist/period violinist and has performed, broadcast and recorded with The Academy of Ancient Music and other period-ensembles. Since his pioneering book Violin Technique and Performance Practice in the Late Eighteenth and Early Nineteenth Centuries (1985) he has published widely on issues of performance practice, organology, music of the 'long eighteenth century', violinists, chamber music and string playing in general. His more recent major publications include The Cambridge Companion to the String Quartet (2003), The Early Violin and Viola (2001), a monograph on Beethoven's Violin Concerto (1998) and a co-authored volume (with Colin Lawson) on historical performance (1999), the first of a series of which he is co-editor.
