ALTERA ENIGMA is the Melbourne, Victoria –based jazz fusion influenced progressive metal band of Jason De Ron (the former guitarist of Paramecium), 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. While both Jason and Jeff may be more well known for their metal, with Paramecium and Kekal having both released many critically acclaimed albums of intense, evocative metal, in actual fact both musicians are heavily influenced by jazz and progressive music in all its forms. Altera Enigma was formed as an outlet for Jason and Jeff to work together on music that would push their boundaries, challenge them musically and allow them to broaden their horizons and explore progressive music in all it's forms. In 2006 Altera Enigma released their debut album "Alteration" and in 2007 the band added drummer Jayson Sherlock to the line-up. Altera Enigma utilises modulating time signatures, rich jazz-fusion inspired chord progressions and memorable, emotion driven melodies, and expressive, stunning lead work. 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 to meld their music into a fascinating, emotive, energetic journey via the listeners ears, mind, heart and soul.
