Gular Flutter, Blectum’s first album in four years, is as indebted to her veterinary studies as it is to her collaboration with Blechdom. The title refers to a part of a bird’s throat (ornithology is Blectum’s area of specialization), but it’s easy to locate animal metaphors all over. Every song has its flutters and tics. Blectum shaves beats so razor thin that they lose their bass-ness and become another light, feathery wafer to stack and arrange. She’s clinical in her song-making: Every sound, from fuzzy poofs of static to 8-bit bleeps to the reversed violin (Blectum is classically trained), gets examined under her microscope.
