This is probably the weirdest and the most different, also most fascinating kind of sound I can imagine. It's a mix of buddhist chanting, japanese folk, indonesian gamean music and synthetizers. The band's most well-known and probably best work is Akira soundtrack. Nevertehless, I would recommend the people who are new to the band to download and listen in the order of this post.
"Geinoh Yamashirogumi (Japanese: 芸能山城組, Geinō Yamashirogumi) is a Japanese musical collective founded on January 19, 1974 by Tsutomu Ōhashi, consisting of hundreds of people from all walks of life: journalists, doctors, engineers, students, businessmen, etc.
They are known for both their faithful re-creations of folk music from around the world, as well as their fusion of various traditional musical styles with modern instrumentation and synthesizers." Links taken from Zombiepaper's list on RYM .
