Royal Thunder is an American rock band from Atlanta, Georgia, founded in 2004 by guitarist Josh Weaver.

[4] After forming in 2004 with Weaver on guitar, Mlny Parsonz on vocals and bass, and Jesse Stuber on drums, Royal Thunder self-released a self-titled EP in 2009, after which the band was signed to Relapse Records.

[10] Crooked Doors was noted as being more varied and progressive than its predecessor,[11] while Parsonz's bluesy, waling voice and harrowing lyrics gained the attention of critics.

In a review of the album, Rolling Stone praised Parsonz for her "raspy, powerful wail [which] is one of the most moving voices in rock right now," and noted that the band "has found its sound.

"[3] Classic Rock Magazine described the album as the band's most powerful yet, with "a shifting musical bedrock over which Parsonz... delivers the kind of vocals – sometimes armoured, sometimes vulnerable – that can emote, transport and illuminate in equal measure.
