With their lineup finally solidified, the trio signed to England's Cacophonous Records, where they released their next three full-lengths: Infidel Art (1995), Hail Horror Hail (1997), and Scenario IV: Dread Dreams (1999); a mini-CD, Ghastly Funeral Theatre, also came out on Cacophonous in 1997. Over the course of these albums, Sigh steadily incorporated more diverse elements into their sound, including pianos, female choirs, classically inspired orchestrations (though not the bombastic, Wagner-ian sort favored by many European bands), non-horror movie soundtrack touches, and unexpected mood/style changes that reveal their acknowledged interest in composers John Zorn and Frank Zappa. (Hail Horror Hail even included a defiant warning, apparently meant for more traditionally minded metal listeners, stating that "every sound on [the] album is deliberate, and if you find that some parts of the album are strange, it isn't because the music in itself is strange, but because your conscious self is ill-equipped to comprehend the sounds produced on this recording.") After Scenario IV…, Sigh left the Cacophonous label for Century Media, which released the band's fifth full-length, Imaginary Sonicscape, in the summer of 2001. ~ William York, All Music Guide
