Aqua was released on 8 June 1992 in the United Kingdom by Musidisc and 15 September 1992 in the United States by Great Pyramid Records. The U.S. edition features a modified cover and different track listing, in which "Little Rich Boy" is omitted.

Aqua was recorded at Advision Studios in Brighton, England, and produced by Downes. The cover artwork was designed by Rodney Matthews, known for his work with Eloy and Magnum among others, and featured the group's logotype designed by Roger Dean, who had created the covers of all previous studio recordings.

In April 1991, original vocalist and bassist John Wetton departed from Asia, discouraged by the group's lack of success in the United States. He was replaced by John Payne, who accepted an invitation from keyboard player Geoff Downes to join the group. This duo would eventually lead Asia through to 2006. Although being in an official capacity, two other co-founders, guitarist Steve Howe and drummer Carl Palmer, were involved sporadically, as Howe returned during the sessions having just left Yes again, and Palmer would leave soon, committing to a reunion of Emerson, Lake & Palmer. The line-up was completed by American guitarist Al Pitrelli, who collaborated with Alice Cooper from 1989 to 1991. Several additional musicians were invited as guests, including drummer Simon Phillips.

Recorded live at the Moscow Olympijski Stadium in November 1990, the album includes versions of the King Crimson classics Starless and Book of Saturday.

Phoenix is the tenth studio album by British rock band Asia, released in 2008. It was the first studio recording with the original line-up after the reunion in 2006.

Omega is the eleventh studio album by British rock band Asia, released on 21 April 2010 in Japan by Melodious Frontier and on 23 April 2010 in Europe by Frontiers Records. It was the fourth studio recording with the original line-up and second after the reunion in 2006.

Then & Now is a compilation album by British rock supergroup Asia, released on 13 August 1990 by Geffen Records. It consists of two parts titled as Then and Now. Then comprises songs from the band's first two albums, Asia and Alpha, which featured the band's original line-up of Geoff Downes, Steve Howe, Carl Palmer, and John Wetton. Now comprises songs recorded by the band after Howe's departure (including "Voice of America" from the band's third album, Astra).

Aqua is the fourth studio album by British rock supergroup Asia, released in 1992. It was the first album with longtime vocalist and bassist John Payne.

Started in 1984, it marked the return of Wetton to the group after his firing in September 1983. He had been replaced by Emerson, Lake & Palmer co-founder Greg Lake, temporarily, for the concerts at the Nippon Budokan in Tokyo in December 1983. The opening night of these shows, highly advertised as Asia in Asia, was the first in the history of MTV to be broadcast via satellite transmission. Following a two-month stint, Lake had left Asia and soon Wetton had been convinced to come back. The latter agreed, but made it a condition to his return that Howe depart the line-up. By the time sessions for Astra began, the group had recruited Meyer, a former guitarist of the Swiss hard rock band Krokus. This personnel change marked a shift in musical direction for Asia to a more edgy, slightly arena rock and metal sound. Howe commented in The Steve Howe Guitar Collection (1993) that when the album was done he was asked to play on it but declined because he didn't feel the material was strong.

Alpha is the second studio album by British rock supergroup Asia, released on 12 August 1983 by Geffen Records. It was recorded at Le Studio in Morin-Heights, Quebec, and Manta Sound in Toronto from February to May 1983. Alpha adopted a notably more polished sound with radio-friendly elements and less emphasis on progressive rock sections. Like its multi-platinum predecessor, the album was produced by Mike Stone. It was also the last album to feature the band's original line-up for twenty-five years until Phoenix, which was released in 2008.

Asia are an English rock supergroup formed in London in 1981. The most commercially successful lineup was its original, which consisted of four members of different progressive rock bands who had enjoyed great success in the 1970s: lead vocalist and bassist John Wetton (King Crimson, Uriah Heep and U.K.), guitarist Steve Howe (Yes), keyboardist Geoff Downes (Yes and the Buggles) and drummer Carl Palmer (Emerson, Lake & Palmer). Their self-titled debut album released in 1982, remains their best-selling album and went to number one in several countries. Billboard listed it as the top album in the U.S. in 1982. The lead single from the album, "Heat of the Moment", remains their top charting and best-known song, reaching the top 40 in over a dozen markets. It peaked at #4 in the U.S. on the Billboard Hot 100 and hit #1 on the Billboard Mainstream Rock chart.

Aufgrund der Vermittlung ihres A&R-Repräsentanten John Kalodner hatte die neu gegründete Plattenfirma David Geffens die Band bereits unter Vertrag genommen, bevor Geffen überhaupt eine einzige Note der neuen Stücke gehört hatte. Die Arbeiten am Debütalbum begannen daher schon sehr bald, im Sommer 1981. Die Band nutzte die Londoner Townhouse Studios und die Marcus Studios. Von Anfang an war allen Beteiligten klar, dass man trotz der Vergangenheit der Musiker, die alle bei namhaften Progressive-Rock-Bands (Yes, ELP, King Crimson, UK) gespielt hatten, kein Album in diesem Stil machen wollte. Kürzere, konzisere Lieder und ein einheitlicher, geschlossener Bandsound sollten den radiotauglichen Stil der neuen Band charakterisieren.

Nach einem Versuch, bei der französischen Band Atoll einzusteigen, mit der er drei Nummern, darunter der spätere Asia-Titel Here Comes the Feeling, eingespielt hatte, ging John Wetton auf Anregung seines Managers Brian Lane mit Steve Howe ins Studio, um gemeinsam einige Lieder aufzunehmen. Als Schlagzeuger der neuen Band wurde Carl Palmer engagiert. Geoffrey Downes, der in Folge ein beständiger Autorpartner Wettons wurde, stieß als letzter zur Formation.

Asia's logo and cover artwork were created by Roger Dean, known for his work with Yes (of which guitarist Steve Howe and keyboard player Geoff Downes were previous members) and Uriah Heep (of which bassist/vocalist John Wetton had previously been a member). The debut album's art depicts a sea serpent gazing into a crystal orb.
