Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records  played at  rpm. Vinyl LPs are still issued, though in the 21st century albums sales have mostly focused on compact disc (CD) and MP3 formats. The audio cassette was a format used in the late 1970s through to the 1990s alongside vinyl.

( ) is the third full-length album from Icelandic band Sigur Rós, first released in October 2002. It comprises eight untitled tracks, divided into two parts: the first four tracks are lighter and more optimistic, while the latter four are bleaker and more melancholic. The two halves are divided by a 36-second silence, and the album opens and closes with a click of distortion. Lead singer Jón Þór Birgisson ("Jónsi") sang the album's lyrics entirely in "Hopelandic", a made-up language consisting of gibberish words. ( ) reached No. 51 on the Billboard 200 and was positively received by critics, although some reviewers found the album weaker than the band's previous album Ágætis byrjun.
