Host is the seventh studio album recorded by British band Paradise Lost. The singles "So Much Is Lost" and "Permanent Solution" both have music videos released. Due to an injury, Gregor Mackintosh often played keyboards instead of guitar while touring the album with his guitar technician playing his guitar parts.
The album saw the band moving further away from their previous metal sound to something more akin to a melancholy style of synthpop incorporating downtempo, leftfield, and trance electronic styles. Songs were constructed primarily of programmed drums and synthesizer melodies, with simple, rock-style guitar added for choruses. Vocalist Nick Holmes resolved to simple melodies with his clean singing style, often doubled and harmonized; the resultant material resembled crossover acts like Psykosonik. Holmes commented on this album in 2007, stating:
From Host through to Believe In Nothing, we didn't really kind of know where we were going. We were really in a dilemma.
