He specializes in multi-screen moving image installations, relating to themes connected with natural landscapes.
After training in Chinese Medicine he was a founder member of the charity Open Road, he played with an experimental ambient/techno band Shen in the early 1990s.
The Threshold Artspace, a large and fully networked multi-media 30 screen digital canvas installation in Perth Concert Hall, was conceived by Hamilton & Ashrowan.
Ashrowan describes his work as a process of "honing down the overwhelming complexity of a given landscape place to find within it those images and movements in time that seem to hold the essence of a feeling, a vital intensity.
