Dr. Stefan Östersjö is a leading classical guitarist. Since his debut CD (Swedish Grammy in 1997) he has recorded extensively and toured Europe, the US and Asia. His special fields of interest are interaction with electronics, experiments with stringed instruments other than the classical guitar and collaborative practices, also between different cultures. As a soloist he has cooperated with conductors such as Lothar Zagrosek, Peter Eötvös, Pierre André Valade, Mario Venzago, Franck Ollu and Andrew Manze. He received his doctorate in 2008 on a dissertation on artistic interpretation and contemporary performance practice, SHUT UP 'N' PLAY! Negotiating the Musical Work, and has since then been engaged in artistic research at the Malmö Academy of Music, and since 2009 also at the Orpheus Institute in Ghent, Belgium. Between 2009 and 2012 he participated in (re) thinking Improvisation, a research project supported by VR, the Swedish Research Council. He is now heading a new international research project on musical gesture, Music in Movement, also with support from VR. He is also a member of Landscape Quartet (an artistic research project with support from AHRC) and in a joint project with David Gorton (Royal Academy of Music) and Eric Clarke (Univ of Oxford) within the CMPCP project in the UK. In 2013-14 several new new book chapters are due for publication at Oxford University Press, Cambridge University Press and Leuven University Press. His most recent CD release is "Signal-in-Noise" with The Six Tones, a double CD on dB Productions 2013.
