Altera Enigma

Altera Enigma is an experimental death and progressive metal band formed by Jason De Ron, the former guitarist and front man of Paramaecium, and 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.

Biography
Altera Enigma was formed as an outlet for Jason and Jeff to work together on music that would push their boundaries and challenge them musically. While both Jason and Jeff are more well known for playing metal music, both musicians claim a heavy influence from jazz and progressive music in all its forms. In an interview with NekroBlog, Jason said that, generally, metal has very limited emotional range, and that Altera Enigma is an attempt to break that mold. Kenny Cheong, a jazz fusion bassist who plays a five string fretless, joined the band in 2005 and allowed Altera Enigma to further develop their signature sound.

The band released its first album, Alteration, on 2006.

2007 saw the addition of drummer Jayson Sherlock, formerly of Mortification, Paramaecium, and Horde.

The band is in the process of creating a new album, but progress on the record has been slow due to various events in the band members lives. As of March, 2010, Jeff, who now resides in Calgary, Alberta, Canada, decided that he needed to step away from Altera Enigma, and his contribution to the project is now minimal, although according to Jason DeRon the band will continue to take advantage of his creativity and inventiveness.

As of May 2011, the band have announced that work on their second album is almost complete, with bass, keys, guitars done, and only drums left to record.
