A Retrospective of Sonic Excellence: Yarlung Records Reissues ‘Nostos’ for its 20th Anniversary

Introduction: A Landmark in High-Resolution Audio

In the high-fidelity world of audiophile recording, certain albums serve as benchmarks for both technical prowess and artistic integrity. As Yarlung Records celebrates its 20th anniversary, it has chosen to revisit one of its most pivotal projects: the choral masterwork Nostos. This reissue is not merely a digital remaster; it represents a fundamental re-evaluation of the recording process, utilizing modern archival technology to unlock the hidden potential of a session that originally began as an experimental test.

For Yarlung founder and producer Bob Attiyeh, Nostos holds a deeply personal significance. It was the label’s inaugural choral recording, a project that—despite its humble origins—would go on to define the label’s commitment to capturing the natural, unadorned beauty of acoustic spaces.

Main Facts: The Evolution of a Classic

The 20th Anniversary Edition of Nostos arrives with a significant technical shift. While the original release relied on a hybrid approach, the new edition draws upon the raw, high-resolution source files captured directly via Merging Technologies’ Hapi interface.

The decision to return to the original multi-mic session files was driven by long-time recording engineer Arian Jansen, who maintained that the initial release, while impressive, had left critical sonic information on the table. By bypassing the analog tape path used in the original master—which, while charming, introduced limitations in transparency—the new edition offers a vastly improved sense of spatial imaging, tonal honesty, and dynamic range. This is, in every sense, a "Pure DSD" presentation of the Cal State Fullerton University Singers at the height of their powers.

Chronology: From Experimental Sessions to Milestone Release

The journey of Nostos is a story of serendipity and technical growth.

• 2017: The original recording session takes place at The Valley Performing Arts Center (now known as The Soraya). Initially, the project was designed as a "warm-up" session to test the acoustics of the new hall and experiment with microphone placement ahead of the more demanding All Things Common project with the Pacific Chorale.
• The Interim Years: The Cal State Fullerton University Singers, under the baton of Robert Istad, continued their ascent in the choral world, touring extensively through Russia, the Baltics, and Scandinavia. Nostos served as a snapshot of an ensemble that had perfected their performance through rigorous international touring.
• 2026: In celebration of Yarlung’s two-decade legacy, Attiyeh and Jansen revisited the archives. The team spent weeks re-processing the original Hapi-captured files, utilizing modern software and workflows that did not exist in 2017.
• Current Date: The official 20th Anniversary Edition is released via NativeDSD, marking a new standard for Yarlung’s catalog.

The Artistic Vision: Robert Istad and the Power of Memory

At the heart of Nostos is the leadership of Robert Istad. As the Professor of Music and Director of Choral Studies at California State University, Fullerton, and President of the California Choral Director’s Association, Istad has cemented his reputation as one of the most influential choral conductors in the United States.

When the group entered the recording hall in 2017, they were fresh off a high-stakes international tour. This, according to Attiyeh, is the "secret sauce" of the album. The music was not being read from a page; it was being performed from memory. The choreography that defined their live tour was largely stripped away for the studio, allowing the focus to shift entirely to the acoustic resonance of the hall and the precision of the vocal blend.

Istad’s recent reaction to the remastered edition was one of genuine surprise. Having listened to the new mix at Acoustic Image, he reported being "blown away" by the transparency and the tangible sense of the concert hall’s volume. The restoration has allowed the conductor’s nuance and the singers’ technical control to emerge with unprecedented clarity.

Supporting Data: The Technical Shift

The shift in production philosophy for this reissue is noteworthy for those who follow the "Pure DSD" movement.

The Analog vs. Digital Debate

In the original 2017 release, the team utilized a combination of analog tape captures and digital tracking. Bob Attiyeh has long been a proponent of the Agfa-formula 468 tape, often preferring the "imprint" it provides when the signal is only milliseconds old. However, for this anniversary edition, the team identified that the direct-to-digital Pyramix files captured by the Merging Technologies Hapi interface contained a more accurate representation of the room’s ambient signature.

Venue Acoustics

Yarlung Records has built its reputation on inaugural recordings in world-class venues. The list is extensive:

• Walt Disney Concert Hall: An architectural and acoustic marvel.
• The Soraya (Valley Performing Arts Center): The site of Nostos.
• Camilleri Hall: A staple for Yarlung’s jazz catalog.
• Samueli Theater at Segerstrom Center: Home to over ten Yarlung recordings.
• Rabat, Morocco: The site of Attiyeh’s latest venture with Majid Bekkas.

The ability to capture the "air" of these rooms is the defining characteristic of the Yarlung sound. By refining the digital chain, the Nostos reissue acts as a case study in how archival data can be "future-proofed" through superior processing.

Official Responses and Reflections

Bob Attiyeh, reflecting on the process from his current location in Rabat, Morocco, where he is recording the legendary jazz musician Majid Bekkas, shared his thoughts on the importance of this release:

"I haven’t admitted this before, but Nostos was supposed to be a warm-up. We were testing microphones and hall acoustics. But sometimes, when you approach a project with that kind of low-pressure curiosity, you capture magic. Returning to these files, I felt a responsibility to the ensemble to present their performance in the most honest light possible. Arian Jansen always felt we left something on the table. With this release, we’ve finally reclaimed it."

Attiyeh also acknowledged the role of Executive Producer Leslie Bigos, whose steady hand and support have been a constant throughout Yarlung’s 20-year history.

Implications: The Future of High-Resolution Reissues

The release of the Nostos 20th Anniversary Edition has significant implications for the audiophile community. It suggests a new trend in the industry: the "living archive." Rather than treating a master recording as a static, finished object, labels are increasingly looking at their historical catalogs as raw materials that can be enhanced as digital capture and conversion technologies improve.

For the listener, this means that the "best" version of a performance may not be the one released at the time of the event. As software-defined audio processing continues to evolve, the gap between the listener’s home system and the original concert hall experience is narrowing.

Conclusion: A Testament to Two Decades

As Yarlung Records looks toward the future—with current projects ranging from Moroccan jazz to continued classical collaborations—Nostos serves as a bridge between the label’s formative years and its current status as a leader in high-resolution audio.

Whether one is a devotee of choral music or simply an aficionado of world-class recording techniques, the Nostos 20th Anniversary Edition offers a compelling listening experience. It is a reminder that the best music is often recorded when artists and engineers are at their most curious, and that with enough care and technical evolution, the "magic" captured in a single session can be polished to shine brighter than ever before.

For those interested in the nuance of the new master, Attiyeh invites feedback from the NativeDSD community. "If you are familiar with the original, I would be deeply grateful to hear what you notice in this new version. It is a work of love, and it is meant to be shared."
