He began the process by sculpting riffs on his electric guitar, then bringing in detailed electronic patterns to interlace with them. The synthesized sound of woodwinds and dulcimer glimmer around his thrashing and simmering guitar, forming short but powerful vignettes that feel luminescent and f.......
