The Doors - Morrison Hotel (1970)

Morrison Hotel's return to basics was largely due to the band's frustration with the lengthy recording of The Soft Parade, which took nine months and cost $86,000 (equivalent to $755,036 today), far more expensive than any previous Doors album.
The band was also affected by the album's critical reception. Morrison Hotel leans in a slightly bluesy direction, which the band would fully explore on their next album, L.A. Woman.
Morrison Hotel was recorded between November 1969 and January 1970, with the exception of "Indian Summer", which was recorded on August 19, 1966, for the first album; "Waiting for the Sun" was actually recorded during the recording of the band's third album.
Although Morrison Hotel does not contain any major hits, it does include some of the band's most popular songs, including "Roadhouse Blues" and "Peace Frog," which later became staples on classic rock radio.
