Growing out of an attempt by Benny Andersson and Bjorn Ulvaeus to record together with their respective companions, Agnetha Faltskog and Frida "Anni-Frid" Lyngstad, the first side cut here, "People Need Love," featured the two men singing just as prominently as the women, and was credited to "Bjorn and Benny, Agnetha and Anni-Frid." It was only after its release and the cutting of a further single, "Ring, Ring," that the more familiar sound of the quartet began to coalesce along with the idea of a permanent professional association.
Unreleased in the United States until 1995, this album is more of a generic European pop release than an ABBA release; the music has several unusual attributes, including Andersson and Ulvaeus singing lead on several cuts, and also one original song, the moody ballad "Disillusion," co-authored by Agnetha Faltskog.
Most of what's here is pleasantly upbeat Europop, with unusually good playing and a lot of spirit, all showing the influence of mainstream American and British pop/rock, including the late-era Beatles and early Elton John, and on the title track, a Phil Spector-proportioned production.
Ring Ring was reissued in October of 2001 with extensive notes, state-of-the-art sound, and three bonus tracks: the single B-sides "Merry-Go-Round" and "Santa Rosa" (a smooth piece of California-style rock in the mold of the early Eagles) and the Swedish version of "Ring, Ring" (which charted number one in Sweden to the English version's number two spot).
