Jeff started to play music back in 1989 when he was 15 years old. He began by playing guitar, and actually couldn't play metal riffs yet. In 1990, with his high-school friends, he formed his own band. It was a totally primitive punkish thrash metal band called Obliteration, who just wanted to play fast and extreme metal, and was influenced by early Black Metal/Thrash bands such as Hellhammer/Celtic Frost, early Sodom, and Bathory. He was playing bass, but quickly changed to drums.
He decided to quit this band in 1991, and spend time learning the guitar more seriously. In 1992 he bought his first electric guitar and joined a band called Sonic Warfare, which later changed it's name to Inner Warfare. This was Jeff's first serious band; Inner Warfare wrote their own music, played shows, and also recorded some demos. Inner Warfare disbanded in 1997. Jeff officially joined Kekal in 1996, although he was involved with the band since it formation as a guitarist, vocalist and songwriter. Kekal started to play extreme metal in the early days and gradually progressed into more electronic-influenced experimental/avant-garde rock/metal.
Kekal have released 7 full-length albums ("Beyond the Glimpse of A Dream", "Embrace The Dead", "The Painful Experience", "1000 Thoughts Of Violence", "Acidity", "The Habit of Fire", and the new 2008 album "Audible Minority"), An Official Demo ("Contra Spiritualia Nequitiae") and a split release ("Chaos And Warfare"). Kekal have also released "Spirits From The Ancient Days", which is a collection of early demo recordings as well as a best-of album "Introduce Us to Immortality".
Jeff also owned and run Vision Studio in Jakarta up until 2006, and in addition to his musical responsibilities in Kekal engineers and produces their albums. In 2006 Jeff moved to Canada and now lives in Calgary, near the rocky mountains.
