Hear different lyrics in the corners of your room; build melodies as you walk around your couch; hear hidden parts and build your own chords just by walking through the space around you. Year One is the first spatial album, utilizing the possibilities of augmented reality technology, by D.C. group and label TCW. Upon launching the Year One app, the different sounds and instruments of the songs will populate and begin moving through the space around you. Your movement, tracked by your smartphone, will affect which sounds you hear and change how individual effects are applied to them, making for a different listening experience each time. This final release of the album contains all eight spatial arrangements from TCW, Wall of Trophies, and N.E. Hertzberg. TCW has released a how-to guide for any musician to build their own similar app independently. Alongside the guide, TCW has begun cataloging spatial composition techniques for other musicians to use and contribute to. This guide and techniques can all be found on tcwav.com. TCW released their first spatial album, Inauguration, in early 2017 using smartphone GPS positional tracking, and released a similar guide for building spatial applications.
