Sean Reinert is the drummer of the group Cynic and Gordian Knot. He is known for his technical and creative drumming. In 1991, Reinert and Paul Masvidal (also of Cynic) joined the band Death to record the Human album. After touring with Death, he returned to Cynic. Because of legal ties with the record company, Sean could not play on the next Death album (leading to the famous collaboration of Chuck Shuldiner and new drummer Gene Hoglan which would last for through the next two Death albums).
