For his second offering on Hapna, Toshiya Tsunoda offers up eight environmentally controlled compositions based on two primary elements: field recordings and studio juxtapositions. The first method appears three times, mainly near bodies of water in the United States and Tsunoda's home in Japan. The second method makes up the rest of the album, using sine waves and frequencies mixed with vibrating objects to produce sounds that, while different in delivery, are strikingly similar in tone and texture. Many of these experimental combinations result in drones that subtly shift and offer faint melodies when listened to attentively. ~ Rob Theakston, All Music Guide
