Rain Tree Crow was the name used by the English New Wave band Japan (excluding Rob Dean, who had departed prior to Japan's initial breakup) when they briefly reformed for this one-off project, which would be their final album. It was the first time all four members of the band, David Sylvian, Steve Jansen, Mick Karn and Richard Barbieri, collaborated on a project since the compilation of the 1983 live album Oil on Canvas. Recorded in 1989-1990 and released in April 1991, the majority of the material on their eponymous album was written as a result of group improvisations (aside from 'Blackwater'). There were no pre-rehearsals and the music that emerged was a hybrid of atmospheric ambient ballads in the style of lead singer David Sylvian's contemporaneous albums and more dissonant experimental styles that sometimes echoed the work of Tom Waits and King Crimson.
