In 2017, the world was captivated by the discovery of 'Oumuamua - a celestial wanderer from beyond our solar system. Its elongated shape and mysterious origins were so unique that they sparked speculation. Scientists pondered: could it be an artificial creation? Might 'Oumuamua be something akin to a lightsail a spacecraft propelled by the radiation pressure (or "wind") from stars, originating from a distant, advanced civilization? Lightsails ('Oumuamua) by Clif Walker provides a soundtrack for this intriguing encounter, employing a range of techniques on mallet keyboards and metallics. Both rhythmically and harmonically dense, Walker masterfully evokes a sense of vast space and wonder, sure to elicit goosebumps and offer a substantial challenge for seven medium-advanced players. If 'Oumuamua is truly a creation of an advanced civilization, are they friend or foe? Lightsails ('Oumuamua) is available as a professionally bound printed score and comes with individual parts in PDF format for either printing or tablet viewing.
