Some context: The Cardigans are a Swedish rock band formed in Jonkoping, Sweden, in 1992, by guitarist Peter Svensson, bassist Magnus Sveningsson, drummer Bengt Lagerberg, keyboardist Lars-Olof Johansson and lead singer Nina Persson, with the line-up remaining unchanged to this day. Their debut album Emmerdale (1994) gave them a solid base in their home country and enjoyed some success abroad, especially in Japan. It was not until their second album Life (1995) that an international reputation was secured. Their popularity rose when their single "Lovefool", from the album First Band on the Moon (1996), was included in the soundtrack to the 1996 film Romeo + Juliet.
The Cardigans returned in 2002 to record Long Gone Before Daylight (2003), a collection of songs mainly written by Persson and Svensson. Long Gone Before Daylight became one of the best selling albums in Sweden in 2003. After a two-year hiatus from their last album, it was released in Japan on March 19, 2003 and in Europe on March 24, 2003. Later it was also released in Canada (April 22, 2003) and the United States (May 25, 2004).  The album differs from the band's earlier works. Their familiar "happy" pop sound takes on a change to pop songs with more of an American country music influence. It is a much darker album than their previous works, and quieter than Gran Turismo. Indeed, even lead singer Nina Persson dyed her once light blonde hair to jet black, reflecting the band's change of mood. The album was produced by Per Sunding after the group's regular producer Tore Johanssen stepped down, feeling himself unable to provide the country sound the group wanted.  Criticism was generally mixed to positive. Some found the change of direction welcome, and felt the band had matured, making songs that were even better than other experienced country-pop styled artists. Others missed the old pop sound, and accused the band of possibly being ashamed of their former "happy" pop sound. The first single of the album, "For What It's Worth" was released on February 17, 2003. The second single was "You're the Storm" released on June 2, 2003. The third and final single was "Live and Learn" released on December 3, 2003. In the summer of 2004, The Cardigans toured with Liz Phair, Katy Rose and Charlotte Martin on the Chicks With Attitude tour.  On 28 April 2005 the band's iTunes Originals album was released through iTunes. On 19 October 2005 the band released their sixth album Super Extra Gravity to generally favourable reviews. Super Extra Gravity went straight to the #1 spot on the Swedish album chart and was certified gold (sales over 40,000). After the band finished promotional activities in fall 2006, the band entered an extended hiatus and devoted themselves to other projects.

Some context: Tierney was born on November 19, 1920 in Brooklyn, New York, the daughter of Howard Sherwood Tierney and Belle Lavinia Taylor. She was named after a beloved uncle, who died young. She had an elder brother, Howard Sherwood "Butch" Tierney, Jr., and a younger sister, Patricia "Pat" Tierney. Their father was a successful insurance broker of Irish descent, their mother a former physical education instructor.
Tierney had reportedly started smoking after a screening of her first movie to lower her voice, because she felt, "I sound like an angry Minnie Mouse." She subsequently became a heavy smoker.  With difficult events in her personal life, Tierney struggled for years with episodes of manic depression. In 1943, she gave birth to a daughter, Daria, who was deaf and mentally disabled, the result of a fan breaking a rubella quarantine and infecting the pregnant Tierney while she volunteered at the Hollywood Canteen. In 1953, she suffered problems with concentration, which affected her film appearances. She dropped out of Mogambo and was replaced by Grace Kelly. While playing Anne Scott in The Left Hand of God (1955), opposite Humphrey Bogart, Tierney became ill. Bogart's sister Frances (known as Pat) had suffered from mental illness, so he showed Tierney great sympathy, feeding her lines during the production and encouraging her to seek help.  Tierney consulted a psychiatrist and was admitted to Harkness Pavilion in New York. Later, she went to the Institute of Living in Hartford, Connecticut. After some 27 shock treatments, intended to alleviate severe depression, Tierney fled the facility, but was caught and returned. She later became an outspoken opponent of shock treatment therapy, claiming it had destroyed significant portions of her memory.  In late December 1957, Tierney, from her mother's apartment in Manhattan, stepped onto a ledge 14 stories above ground and remained for about 20 minutes in what was considered a suicide attempt. Police were called, and afterwards Tierney's family arranged for her to be admitted to the Menninger Clinic in Topeka, Kansas. The following year, after treatment for depression, she was released. Afterwards, she worked as a sales girl in a local dress shop with hopes of integrating back into society, but she was recognized by a customer, resulting in sensational newspaper headlines.  Later in 1958, 20th Century-Fox offered Tierney a lead role in Holiday for Lovers (1959), but the stress upon her proved too great, so only days into production, she dropped out of the film and returned to Menninger for a time.
