The Summer Collection is a compilation album by Donna Summer released in 1985 by Mercury Records. Summer had made her name during the era of disco music in the 1970s when she was signed to Casablanca Records. In 1980, she signed to Geffen Records but her success there was not what it had been on Casablanca. In the early 1980s, Casablanca was bought out entirely by Polygram Records, and Summer had returned to them for one studio album. Mercury, another division of Polygram and a sister company to Casablanca, released that album entitled She Works Hard for the Money in 1983. It also released this compilation album in 1985, containing seven of her original disco hits from Casablanca, plus three songs from the aforementioned Mercury Records album.
The Donna Summer Anthology is a double compilation album by the American singer Donna Summer, released by Polygram Records in 1993. The compilation featured the majority of Summer's best known songs right from the start of her success to the present day. Summer had originally made her name during the disco era in the 1970s and in the decade that followed had experimented with different styles. Most of the tracks on this compilation are the original album versions of the songs, which were sometimes edited down for their release as a single. Included for the first time are two remixed tracks from her then previously unreleased I'm a Rainbow album, which had been recorded in 1981 but had been shelved by her record company at the time.
Bad Girls marked the high-water mark in Donna Summer's career, spending six weeks at Number One, going double platinum, and spinning off four Top 40 singles, including the chart-topping title song and "Hot Stuff," which sold two million copies each, and the million-selling, Number Two hit "Dim All the Lights." Producers Giorgio Moroder and Pete Bellotte recognized that disco was going in different directions by the late '70s, and they gave the leadoff one-two punch of "Hot Stuff" and "Bad Girls" a rock edge derived from new wave. The two-LP set was divided into four musically consistent sides, with the rocksteady beat of the first side giving way to a more traditional disco sound on the second side, followed by a third side of ballads, and a fourth side with a more electronic, synthesizer-driven sound that recalled Summer's 1977 hit "I Feel Love."
