Review of Voices from a Locked Room

I've been a fan of early 20th century British music for years, have many recordings of Peter Warlock's works, and have read about Philip Heseltine <no spoilers>. I have NEVER come across any reference to the convoluted plot twists that the movie purports are part of his life story. A drunkard, yes, but a psychotic? Hmmm. Good performances, tho, and perhaps the BEST performance is by Sylvia McNair, whose golden voice graces most of the pop and classical pieces in the soundtrack. (One good Warlock story...he wrote one of his most famous Christmas carols along with a poet friend, and sold it to a newspaper in order to have enough money to get drunk on Christmas.)
