Altera Enigma is the Jazz Fusion influenced Progressive Metal/Rock band of Jason De Ron (the former guitarist of Paramaecium), Jefray Arwadi (guitarist and vocalist of Kekal) and Kenny Cheong, a Jazz Fusion bass player who plays 5 string fretless. These musicians have a career that has seen them record and released nearly 20 albums between them. Altera Enigma utilizes modulating time signatures, rich Jazz-Fusion inspired chord progressions and memorable emotion driven melodies. Always conscious of melody and utilizing tight, powerful arrangements, their music takes listeners on an aural journey via sophisticated harmony and elaborate, engaging rhythms. These musicians draw on the complexity of instrumental bands like Liquid Tension Experiment and Gordian Knot, the energy of Heavy Metal bands such as Iron Maiden, and then fuse it with the emotion and sophistication of Jazz Fusion as the bands strives to meld their music into a fascinating, emotive, energetic journey via the listeners ears, mind, heart and soul.
