Hercules & Love Affair is a dance music project created by Andrew Butler in 2004. Consisting of a rotating cast of performers and musicians, the band work within the genres of house music, disco, techno and nu-disco.

The project’s first LP was released in 2008 with the participation of singer ANOHNI, who also co-wrote some songs on the album. His group’s second album, the relatively low-key Blue Songs, was released in early 2011. After taking Blue Songs on tour, Butler went to Vienna, where he found himself in studio to put down ideas for his third album. Opting this time for a dirtier sound by mixing elements of rough house and techno – which resulted in the album The Feast of the Broken Heart (2014), featuring lead vocal turns from the likes of John Grant, Krystle Warren, and Rouge Mary. The fourth album Omnion appeared in mid-2017, featuring collaborations with Sharon Van Etten, the Horrors' Faris Badwan, and Icelandic vocalist Sísý Ey. Later, Butler would re-teams with ANOHNI after fourteen years since their debut album for the 2022’s In Amber a more darker and denser piece in comparison to the previous albums.
