Dowser is a duo of the two electro-musicians Nagashima Hiroyuki and Terai Masateru.Since their musical approach varies with every piece, their music cannot be described in short, however, it always evokes visual images. Using vintage synthesizers such as EMS, Buchla and latest DSP, the music they produce has sometimes barbaric and sometimes vulnerable feel. They have been working with several leading film directors, including Fukui Shoujin, Ishii Sogo, and Otomo Katsuhiro. Music for Ishii's "Angel Dust" was reviewed "The return of Telemusik( Stockhausen )" on Wire magazine. Nagashima( prepared sampler ) and Terai ( electronics ) are also the members of Big Picture, a project by Phew, legendary Japanese female vocalist.
