Come From Heaven

They've named a song ''Nyquil,'' but English duo Corin Dingley and Andy Jenks' electronic etherea isn't the sleep-inducing bore you might expect. Thank unjustly unknown guest vocalists Wendy Stubbs, Helen White, and Martin Barnard; all have lovely, lonely voices that make Come From Heaven's otherwise uneventful soundscapes like ''Delaney'' and ''Somewhere Not Here'' as tuneful as they are moody.
