The group is one of Sweden's most successful music acts, both nationally and internationally, achieving a series of hits since their debut single in 1999.

The group gained international recognition in 2000 with their song "Crying at the Discoteque," which charted in the USA, Brazil, Australia, Japan, and most European countries.

The group formed in 1998 with three members: Andreas Lundstedt, Tess Merkel, and Annika "Annikafiore" Kjærgaard (née Johansson).

Both singles appeared on their album, Casino, which was written and produced by fellow Swedes Alexander Bard[1] and Anders Hansson.

Lundstedt pursued musicals and took on the lead role in Saturday Night Fever, while Tess became a professional poker player.

[7] In May 2007, the band performed in London at the nightclub G-A-Y, alongside Swedish colleagues BWO and Army of Lovers, with their friend Lina Hedlund joining them on stage.

Although not officially released as a single, the song charted on Swedish iTunes due to Alcazar's popularity in their home country.

Alcazar has participated in Melodifestivalen, the annual competition that selects Sweden's entries for the Eurovision Song Contest, on five occasions.

In 2003, their song "Not a Sinner, Nor a Saint" initially failed to qualify for the final but received a wildcard in the second chance round, ultimately finishing 3rd overall.

In the final held at Globen, Alcazar placed third with the regional juries and fourth in the televote, ultimately finishing fifth overall.

The group also participated in Melodifestivalen 2010 with the song "Headlines", written and produced by Tony Nilsson and Peter Boström.

[14] On 23 February 2013, Alcazar reunited for a "best of hits" performance in Melodifestivalen 2013 in Malmö, joined by Swedish singer Danny Saucedo.

[21] Alcazar reformed in July 2007 to perform at the London Astoria as part of a celebration of Swedish music organized by producer Alexander Bard, known for his work with Army of Lovers.

During the G-A-Y event on 21 July 2007, they performed alongside BWO and a reformed cult band, Army of Lovers.

[22] Despite the successful performance, Andreas Lundstedt did not confirm any plans for a full reunion, only suggesting future one-off appearances at G-A-Y events.

[18] The band performed again on 5 July 2008 at G-A-Y Astoria for Pride London 2008, singing "This Is the World We Live In", "Sexual Guarantee/Don't You Want Me", and "Crying at the Discoteque" after BWO.
