About the musical techniques used in STALKER/ZONE, it is worth noting the use of the piano stringboard, already employed in previous works, but here often in combined use with audio effects (live electronics) obtained via pedals. Moreover, in this work, the vast majority of the piano stringboard parts are played using some objects (glass spheres, plectrums, putty knives, brushes of different sizes, bottlenecks, and a rubber hammer).
