How 21 by Adele Was Mixed and Mastered

Editorial note: worldwide album-sales totals are estimates and rankings change. This study uses documented credits and interviews; it does not invent plugin chains, secret presets or exact settings that the team has never published.

Album and production credits

• Artist: Adele
• Album: 21
• Release: 2011
• Producer(s): Adele with Paul Epworth, Rick Rubin, Jim Abbiss and others
• Mixing: Tom Elmhirst, Jim Abbiss, Ian Dowling and others
• Mastering: Tom Coyne

The album changes producers without losing intimacy. Vocal storytelling is the invariant; production expands or contracts around it.

What the production and mix reveal

1. Tom Elmhirst’s mixes keep consonants and breath detail present while controlling the power of Adele’s upper register.
2. “Rolling in the Deep” builds weight through layered rhythm and response vocals; “Someone Like You” protects the instability of voice and piano.
3. Tom Coyne’s master creates commercial continuity across deliberately different production aesthetics.

What modern mixers can learn

Use automation and selective dynamic control to keep an expressive vocal close; a single aggressive compressor setting is rarely the whole answer.

Use a level-matched reference when applying this lesson. Compare vocal position, bass extension, transient shape, stereo movement and section-to-section contrast—not just loudness. A historic record is a reference for decisions, not a preset to copy blindly.

Applying the idea in MixingMusic

Upload stems when you need a new balance, or upload a stereo premix when the balance already works. Start with the Neutral preset for material that already contains the intended effects; then adjust only what the song objectively needs. For a collection of songs, Album Mode is the safer place to evaluate continuity without forcing every track into identical processing.
