This is a thriller from England's Hammer studios and not a TV movie as some comments have suggested. A woman arrives at a country estate to write a thesis on a dead classical composer. While she's there, she becomes involved in a twisted tale involving infidelity and murder and finds her own life in jeopardy. Warner Brothers released this uncut and rated R but later cut it down to PG and used it on double bills with Dracula AD 72 and WHEN DINOSAURS RULED THE EARTH. WHEN DINOSAURS was cut down to a G rating and seeing as Warner's is releasing Dracula AD later this year, maybe they can get around to their other remaining Hammer properties. It would be great to see CRESCENDO AND DINOSAURS get uncut R1 DVD releases.
