Fifth Dimension (album)

Fifth Dimension is the third album by the American rock band the Byrds and was released in July 1966 on Columbia Records. Most of the album was recorded following the February 1966 departure of the band's principal songwriter Gene Clark. In an attempt to compensate for Clark's absence, guitarists Jim McGuinn and David Crosby increased their songwriting output. In spite of this, the loss of Clark resulted in an album with four cover versions and an instrumental, which critics have described as "wildly uneven" and "awkward and scattered". However, it was the first Byrds album not to include any songs written by Bob Dylan, whose material had previously been a mainstay of the band's repertoire.

The album peaked at number 24 on the Billboard Top LPs chart and reached number 27 on the UK Albums Chart. Two preceding singles, "Eight Miles High" and "5D (Fifth Dimension)", were included on the album, with the former just missing the Top 10 of the Billboard singles chart. Additionally, a third single taken from the album, "Mr. Spaceman", managed to reach the U.S. Top 40. Upon release, Fifth Dimension was widely regarded as the band's most experimental album to date and is today considered by critics to be influential in originating the musical genre of psychedelic rock.
