Resonance Lines, a term borrowed loosely from physics, refers to the energy emitted or absorbed by an atom as it transitions between different energy states. This is a unique and innate quality for each type of atom that can only be measured and observed under the right enabling circumstances. An ideal artistic collaboration feels like the discovery and realization of deeply held potential for shared creativity-a sympathetic resonance or surge of energy in the colloquial sense-that is revealed when the right conditions are in place. It may feel lucky or it may feel destined, and in special cases, the "resonating" artists are able to nurture and develop their complementary qualities with lasting effect. This album is a collection of music grown of such pairings, collaborations between composers and cellists joined by shared experiences that lead to creative sparks, unique musical gestures, and new sound worlds.
