Exotica is a musical genre, named after the 1957 Martin Denny album of the same title, popular during the 50s to mid-60s, typically with suburban Americans who came of age during World War II. The musical colloquialism exotica means tropical ersatz, the non-native, pseudo experience of insular Oceania, Southeast Asia, Hawaii, Amazonia, the Andes and tribal Africa. The distinctive sound of exotica relies on a variety of instruments: conga, bongos, vibes, Indonesian and Burmese gongs, boo bams (bamboo sticks), Tahitian log, Chinese bell tree and Japanese kotos. Additionally intrinsic to the sound of exotica are bird calls, big-cat roars, and even primate shrieks which invoke the dangers of the jungle.
