Before and After Science

Before and After Science is the fifth studio album by British musician Brian Eno. Produced by Eno and Rhett Davies, it was originally released by Polydor Records in December 1977. Unlike Eno's previous albums which were written and recorded quickly, the album took over two years to complete. Several guest musicians from the United Kingdom and Germany helped with the album, including members of Roxy Music, Free, Fairport Convention, Can and Cluster. Over one hundred tracks were written with only ten making the album's final cut. The musical styles of the album range from energetic and jagged to the later tracks which are more languid and pastoral.

The album marks Eno's last foray into rock music for the 1970s as a solo artist, with all his remaining albums of the decade showcasing more of Eno's avant-garde and ambient music, which was hinted at on the second half of Before and After Science. The album was Eno's second to chart in the United States. The song "King's Lead Hat", an anagram for Talking Heads, was remixed and released as a single although it didn't chart in the United Kingdom. Both initial and more recent critical response to the album was positive with several critics calling it one of Eno's best works.
