'Journey Test' is composer and pianist Tristan Eckerson's first album under the moniker of Purple Decades, his new ambient project. While his past work has focused largely on solo piano, Purple Decades is an exploration into soundscapes, electronic textures, and hypnotic musical environments. While many tracks on the album still feature piano or keyboards in some form, the compositional approach is accompanied by extensive work with reverb, foley, and orchestral electronic arrangements, and some tracks have eschewed the piano completely, opting instead for immersive and texturally rich auditory journeys.
