The Origens project, conceived by Alessandro Aru, is a psychedelic progressive rock album with visceral instrumentals that brings together members of several bands from the rock music scene in Alagoas. With his unique style, inspired by icons of the instrument in rock and roll – such as John Paul Jones (Led Zeppelin), John Entwistle (The Who) and Jack Bruce (Cream) –, the bassist is an important figure in rock in Alagoas.
