Leonard "Leo" Setiawan is mainly known as a former guitarist for progressive metal band Kekal.

His main occupation is civil engineer and he owns and operates a building development firm in Jakarta, Indonesia.

Leo joined Kekal in 1996, just after the band released their official demo, Contra Spiritualia Nequitiae.

Shortly after this album was released, Leo Setiawan left the band and moved to Melbourne, where he pursued his master's degree in Civil Engineering.
