Pinkcourtesyphone returns with Description of Problem, its 4th full length and most vital, disconcerting collection to date. If its debut, 2012’s Foley Folly Folio, sounded less like an echo chamber than a shattered hall of mirrors, and this year’s A Ravishment of Mirror captured the weary sighs of washed-up starlets gazing out into the perfumed smog of Los Angeles, Description of Problem is a busier signal indeed.

An unprecedented group of vocal collaborators—including William Basinski’s haunting voicemails, AGF, Evelina Domnitch, and the legendary Cosey Fanni Tutti (Chris & Cosey, Throbbing Gristle, CTI) and Kid Congo Powers (The Gun Club, The Cramps, The Bad Seeds)—join Pinkcourtesyphone’s party line for obsession and revenge musings and ache all down the wires. Sound artist Richard Chartier monitors the call, offering the sounds of chiffon rustling, the buzzing void of messages never received, and the fey wonder of calculated desire and boredom.
