Although now called iZLER, the musician has a number of credits under the name of Fil Eisler. He is Czech born and has a wealth of experience as a guitarist and instrumentalist, having toured and recorded with Robbie Williams and worked with many other well-known artists (Dave Stewart, Imogen Heap, Kylie Minogue, Tom Jones, Brian May, to name a few). As a musician and song-writer his work has been heard on a number of television series including "ER", and several films including "Redline" and "My Best Friend's Girl". He has also provided the soundtrack for various films, particularly shorts, documentaries and the independent production "Humboldt County". Along his varied career path, he has worked with established composers including Marco Beltrami and Klaus Badelt, and was one of six composers invited to attend the Sundance Film Composer's Lab in 2008.
In 2010 iZLER scored "Thomas" about a boy who lives on a farm with his parents and a dog. This short was part-financed by the UK Film Council New Cinema Fund and was premiered at the Sao Paulo International Short Film Festival. Since then the composer has been busy with a few feature films including "The Hammer" an inspirational wrestling drama, "On The Ice" a thriller set in Alaska, "Natural Selection" with Curt (or Curtis) Schneider, and most of the music for the TV series "Revenge" which has now been running for 3 years.
