Altera Enigma

Altera Enigma is a Christian metal band formed by Melbourne, Australia-based Jason De Ron, the former guitarist and front man of Paramaecium, and Jakarta, Indonesia native Jefray Arwadi, former guitarist, vocalist, and front man of Kekal. Both of these musicians have a career that has seen them record and release nearly 20 albums between them. According to Jason De Ron, the name Altera Enigma was chosen because it represents something mysterious and unique. Kenny Cheong, a jazz fusion bassist, joined the project in 2005, and Altera Enigma's first album was released in 2006. Jayson Sherlock, a former band-mate of De Ron in Paramecium and also a former member of the band Mortification and the sole member of Horde, joined on drums in 2007. In 2009, Jeff Arwadi, having relocated from Indonesia to Canada in 2007, decided to step down from the project.
