Australia’s Eddy Current Suppression Ring has been gathering fans like lint on corduroy with its fantastically rough-edged, exhilaratingly loose, modern-day take on post-punk garage rock. After three studio albums, So Many Things comes along like a treasure chest of hard-to-find singles, compilation tracks, and other rarities that will more than tide fans over until the next studio outing. It’s a bumpy ride ahead, a thrilling jumble of styles that opens with their rare first single, “So Many Things,” a hilarious tune that sounds more like a grizzled pub band stumbling through a drunken set than a bunch of young punk upstarts. Snazzy surf guitar inflections buzz on “That Time of Day,” while “Noise in My Head” conjures The Kinks gone punk and combustible fumes waft from a cover of The Pagans’ “Boy, Can I Dance Good.” The Wire-inflected guitars on “Precious Rose” and the raucous implosion of “Get Up Morning” sound great here, nestled amongst lesser-known treats like a raw B-side track from their first single, “You Don’t Care,” and their cover of The Go-Go’s track “We Got the Beat” from a Record Store Day single released in 2011.
