Italian experimental power electronics project formed by Andrea Chiaravalli with the assistance of Paolo Bandera and Eraldo Bernocchi. Many of the early recordings were heavily influenced by thrash and speed metal. Since 1994 the project has primarily been just Andrea with the assistance of Paolo Bandera. Though inactive since 1999, there are plans for the project resurfacing in 2008.
Iugula-Thor has often been closely tied with Sigillum S, as Andrea Chiaravalli has often assisted that project in the studio and live, especially during the late 1980s and early 1990s.
