Every so often, a piece of music comes along that defines a moment in popular culture history: Johann Strauss' operetta Die Fledermaus did this in Vienna in the 1870s; Jerome Kern's Show Boat did it for Broadway musicals of the 1920s; and the Beatles' Sgt. Pepper's Lonely Hearts Club Band album served this purpose for the era of psychedelic music in the 1960s. Saturday Night Fever, although hardly as prodigious an artistic achievement as those precursors, was precisely that kind of musical phenomenon for the second half of the '70s – ironically, at the time before its release, the disco boom had seemingly run its course, primarily in Europe, and was confined mostly to black culture and the gay underground in America…
The original double-LP version of this compilation was one of the most generous in the Bee Gees' catalog, assembling 20 of their biggest disco-era hits and most important album tracks in one place, all while the disco boom was still alive in a lot of places. The expanded Reprise double-CD edition of this collection, released in September of 2007, boosts the original compilation's running time by more than 30 minutes, most of the latter made up of remixes and alternate mixes of established hits, such as a 12" promo version and a Teddybears remix of "Stayin' Alive," a Jason Bentley/Philip Steir remix of "You Should Be Dancing," a Count De Money remix of "If I Can't Have You," a Future Funk Squad remix of "Night Fever," and a Supreme Beings of Leisure remix of "How Deep Is Your Love." There's also one previously unissued track, "Warm Ride," without a word of mention about when or where it came from – in its defense, it's as good a song as anything the Bee Gees actually released in the second half of the '70s.
Their previous album having scarcely made a ripple and, now, hitless for two years, the Bee Gees went for a new sound in the hands of producer Arif Mardin. The result was Mr. Natural, the sultriest and most soulful record they had ever delivered up to that time. Shedding their pop sensibilities here and singing in a freer, more soulful idiom (with a strong Philadelphia soul influence) on songs such as "Throw a Penny," and with a funky beat backing them up on a lot of this record, the group is scarcely recognizable in relation to their previous work. Mr. Natural was the liveliest, most invigorating body of music to come from the group since their debut, but it also had moments of extraordinary sensuality, most notably "Charade" and "Had a Lot of Love Last Night."
In its original form, this double-LP compilation was a very generous repackaging of four years' worth of hits and notable album tracks, plus the Andy Gibb-authored "(Our Love) Don't Throw It All Away." It was a perfect distillation of the sound that had put the Bee Gees on top of the pop music world from 1975 onward. At the time, it did elicit some unspoken resentment from older fans who knew their hits from the 1960s, but as a collection of first-rate '70s dance music it was unimpeachable. It's also a statement of just how successful the Bee Gees were at the time that this was a double LP, representing just those four years, and how generous the group and RSO Records could afford to be – indeed, anything less would have seemed like exploitation of the fans, but extending it out past the obvious hits (including the Saturday Night Fever material) made this collection an event of sorts, and a release that could stand alongside their albums from Mr. Natural (where their '70s sound really begins) through Spirits Having Flown.
The Bee Gees were a music group formed in 1958, featuring brothers Barry, Robin, and Maurice Gibb. The trio were especially successful as a popular music act in the late 1960s and early 1970s, and later as prominent performers of the disco music era in the mid-to-late 1970s. The group sang recognisable three-part tight harmonies; Robin's clear vibrato lead vocals were a hallmark of their earlier hits, while Barry's R&B falsetto became their signature sound during the mid-to-late 1970s and 1980s. The Bee Gees wrote all of their own hits, as well as writing and producing several major hits for other artists.
