Ask Gotye about his new album Making Mirrors and he’ll speak not of songs, but of sounds. He’ll describe the various valves through which strings and choirs cycle on his Lowrey Cotillion, a vintage organ bought for 100 bucks in a second-hand shop that features on the record. Or how he constructed a bassline by sampling the Winton Musical Fence, an unlikely instrument he discovered in the outback of Queensland, Australia, comprised of five large metal strings attached to wooden fence posts and a resonant chamber. He may mention the horn break from a traditional Taiwanese folk song he discovered on a 1970s Cathay Pacific promotional record, which he sampled, sped up and dubbed out, before introducing it to some Turkish drum sounds. Or the unique, virtual versions of acoustic instruments - among them a chromaharp and an mbira - he created by painstakingly multisampling every note.
