The Berlin Trilogy consists of three studio albums by English musician David Bowie: Low, "Heroes" (both 1977) and Lodger (1979). Bowie recorded the albums in collaboration with English musician Brian Eno and American producer Tony Visconti. The trilogy originated following Bowie's move from Los Angeles to Europe with American singer Iggy Pop to rid themselves of worsening drug addiction. Influences included the German krautrock scene and the recent ambient releases of Eno.
Both Low and "Heroes" experiment with electronic and ambient music, with conventional tracks on side one and instrumental pieces on side two. Lodger features a wide variety of musical styles with more accessible songs throughout; both sides are split thematically by the lyrics. King Crimson guitarists Robert Fripp and Adrian Belew contributed lead guitar to "Heroes" and Lodger, respectively. During the period, Bowie also co-wrote and produced Iggy Pop's debut solo album The Idiot (1977) and follow-up Lust for Life (also 1977); the former features a sound similar to that which Bowie explored on the trilogy.
Bowie began referring to the three albums as a Berlin-centred trilogy during the promotion of Lodger, although "Heroes" was the only instalment recorded completely in the city; Low was recorded mostly in France, while Lodger was recorded in Switzerland and New York City. Though considered significant in artistic terms, the trilogy has proven less successful commercially. Bowie would later call the trilogy's music his "DNA".
The albums of the trilogy received mixed reviews on release but garnered massive acclaim over time and have proven highly influential. While Low provided a major influence on the post-punk genre, inspiring artists like Joy Division and Gary Numan, elements of Lodger have been identified as a precursor to an increased interest in world music. The American composer and pianist Philip Glass adapted the three albums into classical symphonies. They were remastered in 2017 as part of the A New Career in a New Town (1977–1982) box set.
