ERI II is theremin diva. All the performances are due to Etherwave Pro Theremin that Dr.Bob Moog designed. ERI has an absolute pitch and a relative musical sensitivity. It plays on the space and the manipulation melody is played freely. "DenshiOn" album was produced only with Theremin and moog Synthesizer. Mr.ISAO TOMITA composed "#9 Shin Nihon Kikou". "#3 Sukiyaki Song" is a tune of chart No.1 of Billboard in 1963. Q: Is the theremin a Synthesizer keyboard? A: There are neither a physical keyboard nor a bowstring. It is 'Intuition musical instruments' that controls a slight electric wave around two antennas. ERI's Official Website http://www.theremin.org/ Album Information http://www.tapstep.com/cd/0011e/
