I will confess up front that I’ve always been a champion of Sheehan’s work. That goes back to the time he gave me a copy of his first album, Paradigm Shift, which he made in his little dingy Newtown flat on a computer and guitars. I was impressed then and always have been by his experimental approach and continued scientific ‘bent’ to his music. No doubt commissions with big hitters like NASA (3D Planetarium shows) and creating for exhibits and rollercoaster theme park rides and Weta workshop projects have influenced his compositional viewpoint, as have travel, especially to India a few years back. And his work has always been revolved around space, and alternatively, more grounded themes like ecology and humankind’s exploitation of our planet.
