Decisive · Metal Branches
Iron Maiden
NWOBHM band formed in London in 1975. The Dickinson–Murray–Smith twin-guitar years and The Number of the Beast (1982) fixed Harris gallop rhythm and concept lyrics as a global touring metal sound.

Landmark

Gallop and twin lead in NWOBHM
Harris’s eighth-note bass gallop, Murray/Smith dual leads, and concept lyrics define Iron Maiden’s sound. The Number of the Beast (1982) takes NWOBHM from clubs to global touring without thrash BPM. Eddie the mascot sits beside the riffs as visual branding.
02 / 06
Di'Anno bark to Dickinson range
Paul Di'Anno fronts Iron Maiden and Killers with a street bark. Bruce Dickinson joins in 1981; The Number of the Beast brings a wider mid-high range and longer forms. The singer swap keeps Harris’s gallop writing in place.
03 / 06
The Trooper: gallop reference
Open gallop riff, twin-lead harmony, Crimean War lyric. McBrain-era drums. One cut that shows Maiden’s rhythm and dual-guitar method clearly. Run to the Hills and Hallowed Be Thy Name sit as Beast-era companions.

04 / 06
Harris pocket, twin harmony leads
Harris writes and drives from bass. Murray and Smith trade harmony leads more than shred contests. Dickinson’s mid-high range carries narrative lyrics over the gallop. The Di'Anno chapter remains the street-metal citation.

05 / 06
Identity before the new singer
Harris’s hard-line metal claim and Dickinson’s “already had identity” line mark continuity through the vocal swap. Quotes document method, not mystique.
06 / 06
Arena metal before thrash peak
Metallica and other 80s metal acts cite gallop rhythm and twin-lead writing. Maiden keep concept albums and long tours as a stable live practice. NWOBHM scaled without losing the Harris pocket. Lars Ulrich, quoted in the Chinese edition: his heart and soul had gone to Britain, to Iron Maiden. The book later pairs Maiden with Metallica as the arena-metal acts still touring at that scale after the 1990s.
