Archiva is a two-volume collection of out-takes and previously unreleased tracks by British progressive rock band Asia.

On 1 January 1996, when the group returned from the holidays to their recording studio, Electric Palace, in London, they found that a water pipe had burst and had destroyed hundreds of thousands of pounds' worth of equipment.

"Obsession" was composed by Payne and Steve Rodford in November 1991 and was recorded at Advision Studios in Brighton, England, for inclusion on Aqua.

"Moon Under the Water" was written by Downes and Johnny Warman in March 1988 and was one of the tracks recorded by the duo in the basement of Advision Studios in London from 1988 to 1989.

Co-written by Carl Palmer, "The Smoke That Thunders" was the first track recorded in March 1995 at Electric Palace Studios in London for Arena.

"Showdown" is a hit song, which was composed by Jeff Lynne and appeared on the U.S. edition of Electric Light Orchestra album On the Third Day (1973).

As a part of series of remastered and expanded editions, Inside Out Music re-released Archiva as a combined two-disc set, featuring bonus tracks.
