Smith's work was firmly rooted in dub and ragga but also incorporated much of the trip-hop style often associated with Ninja Tune, the U.K. imprint that often distributed Big Dada releases. The MC debuted in 1999 with Brand New Second Hand, a promising album that garnered a sizable amount of attention from the international hip-hop crowd and won Britain's coveted MOBO award. Beginning in late 1999, shortly after the album was released, Smith returned to the studio to begin work on Run Come Save Me, his follow-up. He completed the album and released it on Big Dada in 2001; thanks to his own production on the breakout single "Witness (I Hope)," the album became a British hit and increased his worldwide recognition. It narrowly missed winning the prestigious Mercury Prize and spawned an excellent dub album, Dub Come Save Me, released one year later. His third album, the introverted and somewhat constricted Awfully Deep, appeared in 2005 and peaked within the Top 30 of the U.K. album chart.

The following year's Alternately Deep, featuring remixes and original tracks recorded around the same time as those of its predecessor, was a looser affair. It hinted at the prospect of material with lighter subject matter, but Slime & Reason, released in 2008, was yet another set based on inward-looking, occasionally grim, content. Wrongtom, who produced versions of seven of the album's cuts for the sake of a two-disc edition, was eventually allowed to do the same with tracks from the entirety of Roots Manuva's catalog. The result of this experiment, Duppy Writer, was issued in 2010. 4everevolution, released the following year, was the most diverse Roots Manuva full-length and included appearances from Skunk Anansie's Skin and Cass Lewis. A few singles and EPs appeared in 2012 and 2013, including collaborations with Jamie Cullum, Ill Audio, and Hiem. Smith began working on a new Roots Manuva full-length for release in 2015, with a double A-side single, "Facety 2:11"/"Like a Drum," featuring production by Four Tet and Machinedrum. Preceded by further singles "One Thing" and "Don't Breathe Out," Bleeds (which also featured production by Adrian Sherwood) appeared in late October 2015. ~ Jason Birchmeier & Andy Kellman
