Robert Vrijenhoek is drummer in Dutch metal bands Pyaemia and Disavowed.



Robbert Vrijenhoek joined Disavowed in 1995, shortly after the recordings of Disavowed's first demo "Into the Abscess" which feature original drummer Maarten Winnips.



Due to Robbert Vrijenhoek's wrist injury and a lack of any progress in his recovery the rest of Pyaemia decide to call it a day in December 2005.
