Donnacha's piece for LookListen is called "Elastic Harmonic" and was written in 2005 for violin and orchestra. In Elastic Harmonic the violinist is not set in a dialectical relationship with the orchestra, unlike the traditional romantic violin concerto; rather, Dennehy says, “I was interested in sustaining, and gradually building upon, a continuous quality of sound. The soloist is suspended like a floating body over the orchestra. The sculptures of Eva Hesse (which I love) spring to mind. This is not a game of conflict and resolution, or of dialogue back and forth, but more a landscape of a figure against a shifting ground.”

Donnacha Dennehy is a composer living in Dublin. Born in 1970, he studied music composition with Hormoz Farhat at Trinity College Dublin and at the University of Illinois, USA, where his main teachers were Salvatore Martirano and William Brooks. He pursued further studies in electronic music at the Hague, and at IRCAM, Paris. Returning to Ireland, he founded the Crash Ensemble, Dublin's now-renowned amplified new music band, in 1997. Donnacha is also a lecturer in music composition at Trinity College Dublin.
