Catherine Lamb X Ghost Ensemble ~ Interius/Exterius

Key Takeaways

• Lamb uses 10 Hz-derived just intonation system.
• Ghost Ensemble held year‑long workshops before recording.
• Hammered dulcimer and antiphonal contrabasses broaden timbral palette.
• 33‑minute album condenses original hour‑long performance.
• Greyfade release features high‑fidelity mixing by Branciforte.

Summary

Catherine Lamb and Ghost Ensemble have released *interius/exterius* on Greyfade, a 33‑minute recording that distills a previously hour‑long work. The piece is built on a radical just‑intonation system derived from an inaudible 10 Hz fundamental, creating a relational harmonic field. Ghost Ensemble spent a year in intensive workshops with Lamb, developing novel techniques for instruments including a hammered dulcimer and antiphonal contrabasses. The album showcases high‑fidelity mixing by Joseph Branciforte, emphasizing the microtonal architecture of the composition.

Pulse Analysis

The microtonal foundation of *interius/exterius* pushes the boundaries of just intonation by anchoring every audible pitch to a 10 Hz subsonic fundamental. This approach creates a harmonic lattice that listeners perceive as constantly shifting, yet remains mathematically coherent. By employing a base‑ten series, Lamb invites performers to navigate a sonic terrain where traditional tuning cues disappear, prompting a heightened awareness of overtone interaction and acoustic space.

Collaboration lies at the heart of the project. Ghost Ensemble’s year‑long workshop model allowed each musician to internalize Lamb’s unconventional score, experimenting with scordatura, mid‑piece tuning ring swaps, and precise accordion micro‑adjustments. The inclusion of a hammered dulcimer and antiphonal contrabasses added unique timbral layers, while the intensive rehearsal period fostered a shared vocabulary that translates into a seamless performance. This process exemplifies a growing trend in avant‑garde circles: composers investing time in deep ensemble relationships to realize complex, non‑standard works.

Releasing the album on Greyfade underscores the market’s appetite for high‑resolution, niche recordings. With Joseph Branciforte’s mastering and Matt Sargent’s engineering, the record captures the subtle pitch nuances and spatial dynamics essential to the piece’s impact. Such meticulous production not only serves audiophiles but also sets a benchmark for future experimental releases, encouraging labels to prioritize sonic fidelity alongside artistic innovation.
