Mezzanine is the third studio album by English electronic music group Massive Attack, released on 20 April 1998 by Circa and Virgin Records.

Mezzanine was conceptualised by lead Massive Attack member Robert Del Naja in 1997, who wanted to focus on exploring a darker audiovisual aesthetic with distinct influences.

The production of the album was a stressful process; with tensions arising, it led to disagreements that almost split the group, including discouragement from Andrew Vowles.

As a demonstration of the project's sound, Del Naja initially produced instrumental demos sampling songs by British post-punk bands such as Wire and Gang of Four, who had been familiar to him as artists he had enjoyed as a teenager.

Grant Marshall supported this direction as he wanted to depart from the "urban soul" of their previous album, Protection, but Vowles was sceptical.

The album was originally set to be released in December 1997, but was delayed by four months, with Del Naja spending most of the time in the studio "making tracks, tearing them apart, f***ing [sic] them up, panicking, then starting again.

The album's textured and deep tone relies heavily on abstract and ambient sounds, heavy emphasis on bass, and influences from alternative rock.

Rolling Stone's Barney Hoskyns, although praising the album, pointed to its flaws: "Sometimes rhythm and texture are explored at the expense of memorable tunes, and the absence of the bizarre Tricky [...] only highlights the flat, monotonous rapping of the group's 3-D."[22] Robert Christgau of The Village Voice gave the album a two-star honorable mention rating and selected "Risingson" and "Man Next Door" as highlights.
