Unbehagen is the second studio album by Nina Hagen Band released in 1979 by CBS Records. It is the last album released by the band, before Nina Hagen decided to pursue a solo career. The band kept on performing under the name Spliff. The German title means Discomfort but it can be also seen as a pun on the band name.
The album produced three singles, "African Reggae", "Herrmann hiess er" and "Auf'm Rummel". "Herrmann hiess er" deals with a drug addiction and is believed to be about Hagen's ex-boyfriend Herman Brood. The accompanying music video was also released. The album also contains a German cover version, "Wir leben immer... noch", of Lene Lovich's hit single "Lucky Number". The song "Wenn ich ein Junge wär" was recorded live in April 1979 at the Saarbrücken Congress Hall.
The album was a chart success and was certified Gold in Germany in 1981, selling in over 250,000 copies.
