From dark, wailing experimental folk in the beginning, the sound began to transform and grow, to where it is now compared to the work of Nick Cave, Swans, and Scott Walker.

Their most noticeable recurring output is Simone's charismatic playing of the acoustic guitar,[2] along with martial drum beats characteristic of the neofolk genre, art rock and new wave influences and heavily decadent musical styles.

Slow, dissonant and often melancholic vocals are often contrasted with cabaret-like, somewhat comedic pieces reminiscent of swing revival and neotango sound, bringing on a vast dichotomy in the musical output of the band.

Emotional piano chords are also frequently featured, with occasional violin playing and solos as well as the utilization of a number of different instruments including synthesizers, lutes and pipe organs.

Themes treated by Simone H. deal with searching for self-identity through turbid and untamed exploration of sexuality, stories of breaking up with anger at bitter sarcasm and irony, always touched with nihilism and biting humor.

Sex, sexual abasement, destructive passions, religion, self-destruction, pornography and frankly lewd topics of paraphilia and sadomasochism are expressed in decadent styles of swing revival and acoustic folk ballads.

On 10 November 2023, vocalist Simone Salvatori announced two concerts in Saint Petersburg and Moscow, Russia,[3] to be held on the 14th and 16th of May, 2024 (respectively), amidst the Russian invasion of Ukraine.
