Circus Devils employs a wide spectrum of musical styles, ranging from acid rock to ambient soundscapes.

"[1] Circus Devils was originally conceived in 2001 as a side project to Robert Pollard's main work with Guided by Voices.

Beginning with the release of their first album, Ringworm Interiors, Circus Devils dismissed the styles of Pollard's other musical endeavors for a more experimental approach, taking an ominous and nightmarish tone, exploring the themes of good and evil.

"[1] Like this story, the song lyrics are often unsettling fictional tales of horror delivered within deconstructed rock operas.

[4] Band member and producer Todd Tobias authored a book in 2019 titled Circus Devils: See You Inside, published by Tiny Room in The Netherlands.
