2) Hans Schaaf - Electronic music producer and Mastering Engineer from Berlin, Germany.
3) Honesty is bassist Takakuwa Kiyoshi (Great 3) and guitarist Aida Shigekazu (Foe/EL-MALO), formed in 2003. They’ve released two albums, their latest being American Rock in 2005. Their sound is very similar to that of Great 3 and Curly Giraffe, due to Takakuwa being the main song writer. As of 2008, no plans have been made to continue activity, and have remained that way since late 2006.
