"Alchemy/Bloom" is a series of four pieces centered upon the conception of change that explore the inner dimensions of just, branching ratios of re-tuned stringed instruments. Each piece examines a new mass of mutation, enmeshing the very quiet as well as the very violent. Lingering between glacial drifts, they explore the pure and rhythmic quality of harmony where the masses coalesce.
