In one week’s time, the Time Released Sound record label will release Disintegration, an album by Swoop and Cross. Swoop and Cross is the name under which the London-based musician Ruben Vale records a mix of classical and ambient, or more to the point a music in which those two finds significant common ground. An advance listen to Disintegration is available on Time Released’s soundcloud.com/time-released-sound page. Throughout, solo piano is echoed in myriad ways. There are duplicated lines that suggest a hall of mirrors, and there are faint glimmers that presuppose the presence of an astral accomplice. That latter, ghostly aura lends the already somber, if at times quickly paced, music a nostalgic atmosphere. About two thirds of the way through the track, the piano temporarily disappears, and the glimmer takes over: a hushed, granular cloud through which a flock of birds is heard passing.
