**Band / Album:** Fear Factory — *Demanufacture* (1995)
**Genre:** Industrial Metal

## Overview

Released on June 13, 1995, Fear Factory's *Demanufacture* is the record that gave industrial metal its drumming template. Certified Gold in the United States by the RIAA, the album fused death metal aggression, groove metal riffing, and electronic programming into a genre-defining sound — and at the center of that sound was Raymond Herrera's hybrid acoustic/electronic kit, played with a mechanical precision that no metal drummer had achieved at that tempo before.

*Demanufacture* was recorded at Indigo Ranch Studios in Malibu, California, and produced by Colin Richardson, with additional production and programming from Rhys Fulber of Front Line Assembly. The album's sessions initially began with Ross Robinson, but that material was ultimately scrapped and re-recorded under Richardson's production — a decision that shaped the tighter, more mechanically precise drum sound the finished album is known for.

Herrera's setup for *Demanufacture* was built around Pearl Reference Series drums, fully triggered with ddrum and Roland sensors across the kick drums, snare, and toms, driven by a Pearl Eliminator double pedal and cut through by Zildjian Z Custom cymbals. The title track and "Replica" feature machine-gun double-kick patterns at a level of sixteenth-note consistency that redefined what double bass drumming could sound like in a metal context, directly influencing the generation of industrial and groove metal drummers that followed.

## Gear Breakdown

- **Drums:** Pearl Reference Series (double bass configuration — two 22" x 18" kick drums, fully triggered)
- **Snare:** Pearl Custom 14" x 6.5", steel shell with ddrum trigger

- **Hardware / Pedals:** Pearl Eliminator Double Pedal; ddrum triggers (full kit); Roland drum module; Vater Power 5B sticks
- **Heads:** Remo Pinstripe (bass kick batter), Remo Ambassador (toms batter)
- **Snare tuning:** Medium-high tension — fast mechanical response and cut through dense industrial guitar frequencies

### Pearl Reference Series: Building the Industrial Metal Template

Raymond Herrera's Pearl Reference Series kit on *Demanufacture* established the hybrid acoustic/electronic architecture that would define Fear Factory's sound for the rest of the decade. Maple Reference Series shells gave the kit a resonant acoustic body, while a full complement of ddrum and Roland triggers on every drum layered an electronically processed sample beneath each stroke.

The double 22" kick drum configuration was the engine of the record. On the title track and "Replica," Herrera's kick patterns run in sustained sixteenth-note grids at tempos that made the drums function almost like a sequencer — a rhythmic constant underpinning the guitar riffs. Each stroke fired its ddrum trigger with the same velocity and timing as the last, giving the kick drum sound a machine-like consistency that mirrored the album's lyrical themes of industrial dehumanization.

### Snare: The Mechanical Crack That Defined Industrial Metal

Herrera's Pearl Custom 14" x 6.5" steel-shell snare, fitted with a ddrum trigger, produced the crack that anchors *Demanufacture*'s backbeat throughout tracks like "Self Bias Resistor" and "Zero Signal." The steel shell's fast decay and cutting attack gave the acoustic hit definition even at the album's most tempo-dense passages, while the triggered sample layered an electronically processed snap on top.

### Zildjian Z Custom: Cutting Through the Industrial Wall

The Zildjian Z Custom cymbals Herrera chose for *Demanufacture* were built for exactly the sonic problem the album presented: making cymbal frequencies audible above a dense wall of down-tuned, heavily processed industrial guitars. The china cymbal gets particular emphasis on the album — its aggressive, trashy character driving the most intense sections on "Replica" and "H-K (Hunter-Killer)."

### Pearl Eliminator and Full Trigger System

The Pearl Eliminator double pedal is the mechanical foundation of the album's drumming legacy — Herrera's double-kick patterns on "Replica" and the title track run in sustained sixteenth-note grids that demand near-perfect consistency between both feet. Every drum in the kit carried a trigger feeding a Roland module, and Rhys Fulber's programming background shaped how those signals were processed and blended with the acoustic performance — the single element most responsible for inventing the industrial metal drum sound.
