Intruder is Gary Numan's eighteenth solo studio album and follows 2017's acclaimed Savage: Songs From A Broken World, which became his highest charting set in almost forty years when it debuted at No. 2 on the Official Albums Chart. Whereas Savage depicted earth as a barren wasteland in which humanity and culture had been largely crushed by the effects of global warming, Intruder presents a fresh but complementary narrative. It's a philosophical examination of a potential future apocalypse: the planet can only survive by purging its inhabitants. Intruder was recorded between sessions at Numan's home studio in Los Angeles and at producer Ade Fenton's studio in Bath. It represents their fifth studio album together after Jagged (2006), Dead Sun Rising (2011), Splinter (Songs From A Broken Mind) (2013) and Savage (Songs From A Broken World) (2017).
