Odessa is the sixth studio album by the Bee Gees, a double vinyl LP released in February 1969 in the US and March 1969 in the UK, initially in an opulent red flocked cover with gold lettering. Despite reaching the UK top ten and the US top 20, the album was not particularly well-received, though now is regarded by many as the most significant of the group's 1960s albums. An ambitious project, originally intended as a concept album on the loss of a fictional ship in 1899, it created tension and disagreements in the band regarding the work's direction; finally, a dispute over which song to release as a single led to Robin Gibb temporarily leaving the group.
