"Caulking the Grid" is what I call my shows filling in for other presenters. I approach these shows differently from my regular show "Rock Solid Foundation" and I certainly don't attempt to emulate the shows that I fill in for. I seek to play 30% Australian music and 30% music by non-male artists. I also seek to give some air-play to some emerging Australian artists, as well as showcasing artists that I feel deserve greater exposure such as The Sensational Alex Harvey Band and the Flamin' Groovies.
