In 2018, Matthijs van der Moolen (1994) finished his master studies (cum laude) at the Royal Conservatoire of The Hague, with Charles Toet. He finished two bachelor studies at the same institution in 2016 (classical and historical trombone). He studied the classical trombone with Pete Saunders and Timothy Dowling. The latter also teaches him 19th-century performance practice on original romantic trombones.
Matthijs' main focus is the performance of chamber music, both early and contemporary. He is co-founder of the ensembles Ongestreken and Castello Consort. The Castello Consort specializes in the expressive and virtuosic (chamber) music of the seventeenth century. They recently performed in the foremost (international) concert series and festivals, including the Internationale Händel-Festspiele in Göttingen (DE), Beverley Early Music Festival (UK), Festival d'Ambronay (FR), Festival Barocco è il mondo (IT), BRQ Festival (fringe) in Vantaa (FI), Kongsberg International Organ Summer (NO) and twice in the Fabulous Fringe series of the Utrecht Early Music Festival (NL). Furthermore, they featured in prominent concert series in the Netherlands, such as Musica Antica da Camera and Kasteelconcerten.
Matthijs has played with a variety of other ensembles as well, including Música Temprana, Eik & Linde, het Luthers Bach Ensemble, Concerto da Fusignano and Copper & Zink. He also plays first trombone in the orchestra Ars Musica, and he played with the Orchestra of the 18th Century (collaboration with the conservatory) and with the Youth Orchestra of The Netherlands (NJO).
As a teacher Matthijs is currently connected to Leerorkest Drechtsteden, a project that gives all children at elementary schools the chance to learn an instrument.
