Nine Inch Nails' 2007 release Year Zero will undoubtedly go down in rock history for the way the recording was marketed before its release. It may mark the first time that the advance strategy -- conceived of and executed, for the most part, by NIN auteur Trent Reznor himself with 42 Entertainment -- became part and parcel of the edifice that is the album's concept: an alternate reality game and a possible film project that lasts three years in total make up the rest. Months before the recording's actual issue date, T-shirts appeared with highlighted letters in code that spelled out "I Am Trying To Believe." Hip fans added a dotcom to the words and found a website discussing "The Presence," a shadowy four-fingered hand on the set's cover that appears throughout the booklet, in web discussions of the set, and references to the drug "Parepin," which was allegedly introduced into the water supplies of large cities to make them safe against bio-terror yet induced mass hallucinations as a side effect.
