Pulse Demon is an album by the Japanese noise musician Merzbow. Unlike Venereology, his previous album for Release, this album is not inspired by heavy metal. Outtakes from this album are included on Merzmorphosis.
Critical reaction to Pulse Demon was mixed. Pitchfork Media gave the album's 2003 re-release a glowing score of 8.7/10, their highest rating out of their sparse eight Merzbow album reviews. Calling it an "incomparable classic", the reviewer describes the album as "simply pure sound, viciously unadulterated static", going on to state that "music cannot get much more extreme than this. Maybe John Cage's 4'33", and that's so far to the limit, it's probably cheating. This is the edge of music, of sound in general." Also praised was the album's packaging, being called "more valuable than some people's lives." However, AllMusic's dismissive two-line review was "Merzbow's second American release offers more of the deafening white noise that is his trademark, mastered for maximum loudness. Not for the faint of heart, but ideally suited for the hard of hearing." Being only given 2.5/5 stars, Pulse Demon is one of the four lowest rated of AllMusic's 31 (solo) Merzbow reviews. The A.V. Club's ambivalent review summarized it as "genuinely extreme, downright torturous sounds that are strangely compelling in their shredding intensity."
