Sudden Infant is Joke Lanz, maker of noise and exclusively aggressive conceptual art that connects his warped, heavily political poetry to sparse and ferocious compositions involving marching percussion, unfiltered feedback and skewed tape sounds. Sometimes his new record 'Wolfi's Nightmare' revolves around little more than his voice: the second track, "Hold Me", is a classic tongue-scraping tune involving one lyric and Lanz intoning it through squealing, laughing and scowling. Most tracks manifest with more lyrical weight, though, recalling Michael Gira's hypnotic but knowing songwriting with repeatedly chanted lines like "Ten children die every minute of diarrhoea!". On record, Lanz is helped by Roli Mosimann of Swans and New Order fame, to get that despondent post-punk vibe going. 'Wolfi's Nightmare' is brutal, thought-provoking and unsettling.
