Pizzicato Five (formerly typeset as Pizzicato V and sometimes abbreviated to P5) was a Japanese pop band formed in Tokyo in 1979 by multi-instrumentalists Yasuharu Konishi and Keitaro Takanami.  After some personnel changes in the late 1980s, the band gained international fame as a duo consisting of Konishi and vocalist Maki Nomiya.  The group, widely credited (along with Flipper's Guitar) with spearheading the Shibuya-kei movement of Tokyo in the 1990s, is known for eclectic and energetic compositions that often pay homage to late 1960s English-language pop music.  The catchphrase "A New Stereophonic Sound Spectacular" captured the group's ironic stance and eager attitude.
