The DoelenQuartet has performed in such important Dutch music festivals as the Gergiev Festival, the international Gaudeamus Muziekweek and the Hortus Festival. Åsa Olsson is much in demand as a soloist in many musical genres and styles, working with the Ensemble Intercontemporain, Schönberg Ensemble, Ebony Band, Gesualdo Consort and the Doelen Ensemble. As a freelance percussionist Wilbert Grootenboer has played for many different orchestras and ensembles, these including the Royal Concertgebouw Orchestra, The Rotterdam Philharmonic Orchestra, the German / Dutch ensemble S and Duo Contemporain. The DoelenQuartet is passionate about making this sometimes painful and yet loving compositional struggle audible and keeps in close touch with the latest musical developments. Their collaboration with such composers as Dutilleux, Boesmans, Rihm, Birtwistle, Wagemans and many others is a great source of inspiration to them; that the DoelenQuartet in their turn are an inspiration for their composers can be seen from the passion that resides in the music composed for the quartet. .
