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 He had been replaced by Emerson, Lake & Palmer co-founder Greg Lake, temporarily, for the concerts at the Nippon Budokan in Tokyo in December 1983.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.
