Robert Menczel is a German guitarist and composer.

He interprets, improvises and produces experimental music. Live he combines acoustic and electric guitars with everyday objects and electronics. With his ensemble The Interstring Project he pursues new paths of a contemporary ensemble culture with collective compositions and genre-spanning and interdisciplinary concerts. His artistic vision is that of an open and tolerant musical practice, combining instrumental music, field recordings and digital sounds.

He plays concerts with Ensemble Recherche, at festivals like ECLAT (Stuttgart), PODIUM (Esslingen), Crossroads (Salzburg), Donaueschinger Musiktage, Electroshock (Palermo), Whatever Works (Turku) and in locations like Fylkingen (Stockholm), Badisches Staatstheater (Karlsruhe), Resonart Studio (Tallinn), Opéra de Lyon, Hamburger Bahnhof (Berlin), Nouveau Théâtre de Montreuil.

With Open Source Guitars he has toured in South America (Mexico, Brazil), premiered new pieces (by Henry Fourès, Sarah Nemtsov, i.a.), worked with concept artists (Pablo Wendel, Thomas Putze, i.a.) and participated in the development of international projects (with IRCAM Paris, GMEM Marseille).

He was born in Böblingen and studied at MH Trossingen and RCSM de Madrid with Prof. Michael R. Hampel, Michal Stanikowski, Tillmann Reinbeck and Miguel Trápaga. He completed his Master's degree in 2018 with distinction. Until 2020 he was part of the international Master's program Contemporary Performance and Composition (CoPeCo) with half-year residencies at the music academies in Tallinn, Stockholm, Lyon and Hamburg. He was awarded a special prize at the Iris-Marquardt-Competition 2018 and holds a scholarship by Deutscher Musikrat.
