Mad Professor was contacted by Massive Attack after Protection was released to remix a song for a single. After the single was remixed, the band asked Mad Professor to listen to more of the album to explore the possibility of further remixes. The project then became a track by track remix of almost the entire album. Mad Professor heavily edited the original material to form a slow, pulsating mix in which the beat is emphasized, reverb is extensively used and the occasional vocals (many of the tracks are almost entirely instrumental) fade in-and-out in typical dub fashion.
According to music journalist Robert Christgau, No Protection was the most hyped album during dub music's revival in the mid-1990s. In his review for The Village Voice, he found the music well defined and textured: "It also sustains a convincing gravity—a sense that all these whooshings and clangings and suckings and scrapings and boomings and snatches of tune relate to each other and the rest of the physical universe."
