Charlie Megira’s self-reflexive final album found him far from his Beth She’an Valley home and surrounded by a new cast of Hillbillies. After spending 15 years toying with goth, sound collage, grunge, and dark wave, Boom Chaka Boom Boom is a sprawling mix of plunking country blues, Black Lodge terror, ambient montages, 17th century Lutheran hymns, and noodling spaghetti western kitsch. Deck his soul with gladness.
