Damage, Inc.
The final track on 'Master of Puppets' is a thrash metal monster, but its most sublime moment happens before the first guitar riff even hits. The song's eerie, swelling introduction is composed and performed entirely by Burton. Inspired by a Bach composition,
it features multiple layers of harmonized and volume-swelled bass guitars creating a haunting, classical soundscape. This minute-long piece is a testament to his deep understanding of music theory and his desire to push metal into uncharted territory. It's a moment of pure, isolated artistry that often gets lost in the ensuing sonic assault, but it's one of the most sophisticated things the band ever recorded.
Leper Messiah
Often cited for its heavy, grinding riff and critique of televangelism, 'Leper Messiah' is a masterclass in Burton's powerful sense of groove. While James Hetfield’s guitar provides the jagged rhythm, Cliff’s bass doesn’t just follow along; it prowls underneath, adding a thick, menacing counter-rhythm that gives the song its immense weight. His playing is more about feel than flash here. He locks in with Lars Ulrich's drums to create a foundation that is both incredibly tight and surprisingly funky. There's a brilliant little bass fill hidden in the mix after the guitar solo, a quick, fluid run that showcases his dexterity even when he wasn't in the spotlight.
Escape
This is arguably the most overlooked song in Metallica's early catalog, partly because the band themselves expressed dislike for it, viewing it as a forced attempt at a commercial single. Because of this, many fans skip it. But doing so means missing some of Burton’s most melodic and essential playing. While the guitars maintain a straightforward, driving rock feel, Cliff’s basslines are constantly moving, providing a buoyant, melodic counterpoint that elevates the entire track. It's a perfect example of his ability to serve the song while still injecting his unique personality, proving he could be a hook-driven rock bassist as easily as a thrash metal innovator.
Phantom Lord
On the raw, aggressive debut album 'Kill 'Em All,' moments of melodic subtlety are few and far between. 'Phantom Lord' delivers one of the biggest exceptions, and it's pure Cliff. Right in the middle of the frantic thrash, the song breaks down into a clean, arpeggiated guitar section. This beautiful, almost serene interlude was a compositional piece Burton brought to the band. It was one of the earliest signs of the harmonic and melodic sophistication he would fully unleash on subsequent albums. In the context of such a relentlessly brutal record, this moment stands out as a flash of the future, a hidden clue to the musical evolution that was about to come.
