Live & Remastered (subtitled 20th Anniversary Box Set) is a box set released by the record label of British nightclub Ministry of Sound in September 2011. It was released to celebrate the 20th anniversary of the Ministry of Sound, as part of their 20:20 Project campaign, following the Ministry of Sound's foundation in 1991. Focusing on the early years of the club, the box set contains five discs, each an iconic DJ set performed live at the Ministry of Sound from 1991 to 1994. The DJ sets are mixed by New York DJ veterans Larry Levan, David Morales, Todd Terry, Kenny Carpenter and the club's British co-founder Justin Berkmann, each delivering their own house style. Between them, genres explored include deep house and garage house. The packaging for the set resembles a "flightcase" box, with all the CDs themselves in "record sleeves", whilst the discs themselves are made to look like actual vinyl LPs.

In promotion of the album, a "megamix" of songs from the album was uploaded onto by YouTube by Ministry of Sound, whilst Factmag ran a competition in which free copies were given away. The album was critically well received, who applauded the album's coverage of both the club's early years and the work of the DJs themselves. Time Out New York said the music was "great, both as time capsules and as collections of beautiful dance music." The album peaked at number 50 on the UK Compilation Chart.

London superclub Ministry of Sound celebrated its 20th anniversary in September 2011. In celebration, the club announced the 20:20 Project, which started in March with a multi-media exhibition about the nightclub. Further events include a three-day party in September, an international tour and the release of several commemorative DJ mix compilation albums aimed at different parts of the club's audience. They would release XX: Twenty Years, a four CD compilation of digitally mixed material, each disc covering at a different club night or compilation strand from the club's history, in November 2011, before a sequel album, XX Volume Two, was released in 2012.

Although the XX compilations were aimed at fans throughout their era, their other 20:20 Project anniversary release, Live & Remastered, was aimed more so at earlier goers to the club in its early days. With one reviewer calling it among the club's only releases "aimed at true heads in years," the club sought to create a compilation featuring live mixes of DJs playing at the club from its early days. Many of the club's DJs recorded their sets onto Digital Audio Tape (DAT), and soon enough, the club had extensive recording archive. The club chose to cull several of classic, early DAT-recorded live mixes and remaster them for a new box set. It was decided the set would five different mixes over five discs, therefore being longer than either of the XX compilations, and also the club's previous three-disc anniversary mix albums, One Half of a Whole Decade (1996) and Fifteen Years (2006). Abi Long, Alaine Wingrove, Alex Sparks, Alice Schofield, Gavin Fraser and Sarah Ioannou are credited as the set's "co-ordinators" in the "this album was brought to you by..." section in the liner notes.

The set features five different, "iconic" DJ mix sets recorded live at the Ministry of Sound in the early 1990s; each mix by a different DJ, namely New York DJs Larry Levan, David Morales, Todd Terry, Kenny Carpenter and the club's British co-founder Justin Berkman, respectively. One reviewer noted the mixes date from 1991, whilst Fact Mag said the mixes date from 1990–1994, although the 1990 starting point is a mistake, the club having not opened until 1991. They had not been released before, and were only licensed and remastered for the box. All were recorded on DAT and culled from the club’s extensive recording archive. Bruce Tantum said the mixes were "lovingly restored", and called the set "something of a DJ-festishist's dream, as these sets—from the time when house was morphing from an underground cult genre to the sound of the dance floor—haven't been publicly aired since the time of their creation." Ministry of Sound tracked down the original license owners to the music on the album, described as "no mean feat in itself".

Dance music veteran Larry Levan's mix, recorded in 1991 and comprising fourteen different tracks, was one of the most sought after recordings from the venue, and is said to showcase Levan's aesthetic perfectly: "heaps of soulful vocals and melodic chords proving the strong bond between soul, R&B, gospel and house in his sets." Colin Chapman of Planet Notion said that the mix "includes literally some of the fabric of house music’s defining sound." Among the material on the disc highlighted by reviewers are the piano house of the "Dub of Doom Mix" of "Love Me Forever or Love Me Not" by Trilogy, made up of members of C+C Music Factory, which is followed by two tracks from Italian house producers Soft House Company. After an extended breakdown, "I'll Be Your Friend" by Robert Owens "picks up the groove". Gary Hines' vocal and instrumental ensemble the Sounds of Blackness feature thereafter with "The Pressure".

David Morales’ mix, recorded in the "most productive and most celebrated time" of his career, was noted by one critic for sharing similarities with Levan’s mix. Levan was one of the first to recognize Morales’ talents and the two played together regularly. However, Morales chooses tracks with a "tougher, more percussive edge" than on Levan's mix. Examples of tracks in the mix in this style include Black Sheep’s "Strobelight Honey" and Linden C.'s "Deep Beats Vol. 1". Those two tracks were pointed out by Patrice Knap of Laptop Rockers as examples of obscure tracks, who also noted "there are plenty of classics in the mix as well", naming the vocal-less version of Lil' Louis' "Club Lonely" and Inner City's "Pennies from Heaven" as examples. The end of mix include a "great choice of melodic cuts"; Degrees of Motions' "Do You Want It Right Now" and Chez Damier's "Can You Feel It".

Terry's mix, as is his style to this day, leans heavily on his own productions. Among his own tracks included are "When You Hold Me" and "Hear the Music", the latter credited under the pseudonym Gypsyemen. Carpenter's mix is in a different style, opting for deep house music, including MK's "You Brought Me Love" and Underground Solution's "Luv Dancin'" in the mix, "with time out for a disco break via "Let's Start a Dance" from Bohannon." Berkmann's mix was said to feature "absolutely classic songs", including Earth People's "Reach Up to Mars", Murk's "thumping little mix" of Deee-Lite's "Pussycat Meow", Bobby Konders, and Coco Steel and Lovebomb.
