Ollie is studying the rock cycle right now and last night on our nightly walk we decided to write a rock song about the rock cycle. It was a good excuse to break out the electric guitar that was getting a bit dusty and an opportunity to use igneous and magma in a song which I don't get to do very often. Ollie's Rock Cycle Rock Opera.... Crank it up on the speakers because the bass is bumpin...just saying.
