Another album i found musically and lyrically inspiring of the american west is U2's The Joshua Tree album.
The album has a cinematic quality to it and it evokes a sense of location in particular, the open spaces of America. The mental image of an American desert was inspiration to the group during the albums inception.
The desert, rain, dust and water appear as lyrical motifs throughout the record, the desert itself is used as a metaphor for spiritual drought. For the band the desert was seen as a blank canvas where you can easily add thing.
