Streiber is near enough in name to alien abduction memoirist Whitley Strieber (Communion) that the association becomes part of the listening experience, an implant below the surface. Likely intended, because as “Untitled I” — a track from a tape in Summer Isle’s winter batch — shows, Streiber transmits a distinctly weather-beaten and spooky cast of space music. Flanging tones and heavenly synths invert their usual expansive quality, closing in you instead. A celestial journey ending in a broom closet, the memory recovered only later via dubious hypnosis sessions.
