Attic Thoughts is an instrumentalprogressive rock album by Swedish musicianBo Hansson. The album was recorded during 1974 and 1975 at Studio Decibel in Stockholm, and at Hansson's home, which had virtually become a studio by this point in his career. The album featured contributions from many of the same session musicians and friends that had played on Hansson's previous album, Magician's Hat. In Hansson's native Sweden, Attic Thoughts was released with the Swedish title of Mellanväsen. It was released with its English title in April 1975 by Charisma Records, but was less commercially successful than Hansson's preceding solo albums and failed to reach the charts in the UK or the United States. In addition to featuring Hansson's usual blend of other-worldly progressive rock and fairy tale-like ambiance, Attic Thoughts includes a suite named "Rabbit Music", which was inspired by Richard Adams' novel Watership Down, a subject that Hansson would explore further on his 1977 album Music Inspired by Watership Down.
