"Dan Burke is the leader of Illusion of Safety, the 'group' that succeeded perfectly the marriage between industrial and electroacoustic musics. Thomas Dimuzio has created since his first releases an unusual music made of electronics and electroacoustics with many energies. Both have already released many records separately. Hz is made of extracts of live collaboration during performances in SF Bay Area in 1997. A very good example of improvised live electronics that won't disappoint lovers of these two brilliant musicians." —Forced Exposure
