Boom Boom Satellites (????????? Bun Bun Sateraitsu ) are a Japanese electronic music duo consisting of guitarist and vocalist Michiyuki Kawashima and bassist and programmer Masayuki Nakano. While their music can be mostly classified as big beat or nu skool breaks, and they are heavily influenced by jazz, they are famous for using a lot of electric guitars and the final product often has a strong rock or punk flavor. In 2004, they contributed numerous songs to the soundtrack of the anime film Appleseed, in the 2007 anime film Vexille, and most recently in the Playstation store exclusive and later television anime series Xam'd: Lost Memories. They are currently signed to Sony Music Entertainment Japan, with whom they have released all of their albums in Japan.
