There are at least two bands named Lethean: 1. An Italian psycho-prog ensemble which brought together some of the most talented musicians of northern Tuscany. At first marked by a few line-up shifts, the career of the band encompassed different musical styles, through metal, prog, jazz, and eventually folk. Not dismissing the legacy of King Crimson, Gong, Clear Light, Anekdoten etc. Lethean developed a personal blend of guitar driven prog-rock.
