Jacula's music was considered innovative for the time in progressive circles but considered dark and strange by most fans and analysts of the genre, especially in an era that included the development of groups such as Pink Floyd, Genesis and Gentle Giant, bands which were the basis of the new progressive rock scene.
Because the band was experimental, and had been labeled by founder Antonio Bartoccetti as a youth mistake, Jacula's discography is relatively small.
The group completed two albums: In Cauda Semper Stat Venenum which has a superposition of an organ, piano and other sound effects, and Tardo Pede In Magiam Versus which features Doris Norton's vocals, with a sound influenced by bands of the Italian underground scene such as Le Orme.
In Cauda Semper Stat Venenum was supposedly recorded in 1969 and released in extremely limited numbers, however no original copies have surfaced in collectors circles.
After nearly four decades, Jacula released their third studio album Pre Viam in May, 2011.
