The Onyria alternative rock project, which was created in Italy in 2012 by producer/guitarist Simon J. Gillman and singer Helena, first gained internet fame by publishing rock adaptations of well-known songs. The band gradually shifted from early gothic rock-influenced successful releases to alternative music, embracing rawer thematics and a more basic sound. Their current sound is based on true alternative rock/post-grunge, enhanced with dynamics and variety, while also displaying a level of sensitivity and social critique in their lyrics.
