Call Signs is the third studio album by Melbourne electronica band Black Cab, released in 2009.

[3] In an interview, the band explained the album's sound was inspired by a rare Black Cab tour of Europe in May 2007.

Travelling through the former East Germany in a van, vocalist Andrew Coates and guitarist James Lee were struck by the decrepit villages and rundown cities.

At the same time they were reading Stasiland, Anna Funder's 2004 book about the vast state security apparatus that entangled millions of East Germans.

[3][4] Coates explained: "Stasiland really captured the mentality of living at a time when around 50 percent of East Germans contributed intelligence information, often about their neighbours.
