Arrhythmia is the second studio album from Irish art rock band, Hail the Ghost, which was released on 6 December 2019 on CD, vinyl and digital formats.
The album was recorded, mixed and mastered in JAM Studios, Kells, County Meath in Ireland between 2016 and 2019. The album was produced by Kieran O'Reilly and Martin Quinn.
The album sleeve for Arrhythmia is the work of Italian visual artist, Sveva Robiony.
The album received favourable reviews with The Irish Times referring to the album as a "smart collection of intelligent and sensitive rock...[that will] do the heart and soul good." Hot Press Magazine reported: "Last time round, we described them as "atmospheric indie", but 'Arrhythmia' is composed of bleaker soundscapes, more reminiscent of Joy Division". Kelly Crisp of The Rosebuds said of the album: "this album [Arrhythmia] is luxurious, and a reminder that we're here now, making art and loving beautiful music".
