Tree Helicopter constructs a single extended piece from seven samples of spoken voice, all derived from recordings of Rebekkah Hilgraves reading passages related to the White Rabbit and Bill the Lizard. The samples pass through granular processing, spectral manipulation and other transformative methods to produce drones, textural layers and unrecognizable timbres that no longer sound like speech. One sample receives extreme time-stretching treatment while the others undergo different chains of effect processing, resulting in twenty-two discrete tracks that form the final composition.
The album appears on Sadayatana and Buddhist on Fire, labels associated with experimental sound work and dark ambient practice. C.P. McDill, the sole performer behind Tree Helicopter, has maintained the project since 2004 and positions this release as the third in a series built from voice samples provided by contributors to the Stillstream community. The approach recalls the tradition of musique concrète and voice-based drone work, though the Alice in Wonderland framing gives it a narrative anchor that sets it apart from purely abstract treatments.
This is for listeners who appreciate process-driven composition and the transformation of recognizable sound sources into something fundamentally different. Those drawn to voice-as-material experiments and patient, immersive dark ambient structures will find the single-track format and exclusive source material constraint rewarding rather than limiting.
