I think "Quite Mad" was my favorite, with "Shortcut" and "From the Deep" close behind. The use of repetition was intriguing in all three, generating subtly shifting shades of meaning throughout, though the background music did sometimes grate on me. (I don't want to say "overproduced," but they were getting close to it in places.)
"Christ, I Think It's Death" felt a titch too on-the-nose for my taste. (I mean, yes, supernatural horror is fundamentally metaphorical, of course, and oftentimes it is the fear of death that forms the basis for the creepy feeling it is meant to evoke, but coming right out with it like that felt a bit... soft, almost?)
"Barking Mad" didn't do it for me at all, mostly because I didn't care for the way it posited an apparently abused and developmentally disabled child as the inutterable Other, too alien to ever be understood or related to in any way, and didn't work very hard to redeem that. It felt like a cheap shot. "Quite Mad" had the same premise, in many ways, but shifted the focus of the horror onto the narrator's own creeping fear of their own mental decay ("I ran for fear of the madness"). It's a shame I hit this one and got hung up on its handling of its chosen topic as the first poem; I'd have been thrilled with the whole episode, background music and all, if I hadn't had to overcome this initial bad taste in my mouth to appreciate the others.
Overall, I am solidly in favor of playing with sound and structure for effect and would happily see more like this.
