Effective period / Period of releases: 1992 - 1993

Ultrasonic was the first electronic music project established by Olaf Krautwurst in 1992. Ultrasonic produced mainly electronic body music and electro pop music. Ultrasonic released three regular albums on compact cassette and a limited double compact cassette box set, which was limited to only seven copies. The name Ultrasonic was changed to Inside Agitator in 1994, because of the danger of confusion with the English techno band Ultra-Sonic.
