four album set - limited to 1000 copies. nine inch nails presents ghosts i - iv, a brand new 36 track instrumental collection. almost two hours of new music composed and recorded over an intense ten week period last fall, ghosts i - iv sprawls nine inch nails across a variety of new terrain. this music arrived unexpectedly as the result of an experiment. the rules were as follows: 10 weeks, no clear agenda, no over thinking, everything driven by impulse. whatever happens during that time gets released as... something.
