The success of both singles drove the sales of the album, which eventually reached number two on the UK Albums Chart. Two further singles were released from the album: "Glory Box", which reached number 13 on the UK Singles Chart and "Sour Times", which was released before "Glory Box" but re-released after the success of "Glory Box", also reaching number 13 on its re-release in 1995. The first song released from the album was " Numb". The cover of the album is a still image of vocalist Beth Gibbons taken from To Kill a Dead Man-the short film that the band created-for which the self-composed soundtrack earned the band its record contract. It helped to cement the reputation of Bristol as the capital of trip hop, a nascent genre which was then often referred to simply as "the Bristol sound". For the track " Sour Times", the album samples Lalo Schifrin's "The Danube Incident" and Smokey Brooks' (Henry Brooks, Otis Turner) "Spin It Jig" for "Strangers", Weather Report's ( Wayne Shorter) "Elegant People" for "Wandering Star", War's "Magic Mountain" for "Biscuit", Johnnie Ray's "I'll Never Fall in Love Again" (not the Bacharach/David song) and for " Glory Box", Isaac Hayes' " Ike's Rap II".ĭummy was released in August 1994. In order to create a vintage sound, Barrow said that they distressed the vinyl records they had recorded by "putting them on the studio floor and walking across them and using them like skateboards", and they also recorded the sound through a broken amplifier. They sampled music from other records, but they also recorded their own original music, which was then recorded onto vinyl records before manipulating them on record decks to sample.

The production of the album uses a number of hip-hop techniques, such as sampling, scratching, and loop-making.

According to Barrow, "It was like a light-bulb coming on" when Utley joined them, and they realised they could make their own samples not found on other records, and created one of the most distinctive sounds of the decade. Barrow taught Utley sampling while Utley introduced the band to unusual sounds such as cimbaloms and theremins, which led to an "amalgamation of ideas". Adrian Utley then met Barrow while they were recording at Coach House Studios, heard their first recorded track "It Could Be Sweet", and started exchanging ideas on music. The first song that they finished for the album was "It Could Be Sweet" in 1991. In Bristol, they recorded at the Coach House Studios.

They started recording their first ideas for the songs in Neneh Cherry's kitchen in London while Barrow was hired by her husband Cameron McVey to work on her second album, Homebrew (1992). Geoff Barrow and Beth Gibbons met during an Enterprise Allowance course in February 1991. Worldwide, the album had sold 3.6 million copies by 2008. Dummy was certified triple platinum in the UK in February 2019, and had sold 920,000 copies in the United Kingdom as of September 2020. It is often credited with popularising the trip hop genre, and is frequently cited in lists of the best albums of the 1990s. The album received critical acclaim and won the 1995 Mercury Music Prize. Dummy is the debut studio album by English electronic music band Portishead, released on 22 August 1994 by Go! Beat Records.
