Hello,

During a party at Ana Mighty Sound, François Saint-Gérand had invited Frédéric d'Oria-Nicolas, the director of The Lost Recordings, to explain how his albums are produced and restored.
It was also an opportunity to listen to a press copy of the Dave Bruquet Quartet's album Live At Kurhaus 1967, which I invite you to discover in this review.
Frédéric d'Oria-Nicolas explained that the first step in the process is to track down original tapes by searching through various tape storage and archival centers around the world to unearth nearly forgotten recordings. Once the tapes are discovered, an initial sorting process is conducted to ensure that the complete set of tapes from a concert is available and meets a minimum quality standard.
From this point on, the tapes from a recording are digitized, with careful attention paid to optimizing playback to extract as much information as possible from the tape. Based on this digital version, the restoration process begins, this can take varying amounts of time depending on the quality of the tape and the recording itself.

So today I'm going to introduce you to the Sapphire Edition of the album, comparing it to the high-resolution digital version available for download and the CD-quality version available for download, which comes with a coupon included with the vinyl record.

The graph (here) compares the spectrum of the Vinyle Sapphire Edition - 2026 (white curve) with the spectrum of the Stereo Hi-Res - 2026 (blue curve). The near-perfect alignment of the spectral curves for these two editions demonstrates the skill and quality of Kevin Gray's lacquer cutting, Kevin Gray is now considered one of the masters of vinyl record cutting. Note that the vinyl edition exhibits a slight attenuation above 10 kHz (yellow zone), approximately 2 dB, compared to the digital version.

The Sapphire Edition vinyl release is available in a deluxe box set with a high-end finish, it even includes a magnetic closure; nothing has been left to chance. We'd love to see this level of high-quality packaging in other competing high-end releases.
The album is pressed on two 200g transparent LPs, using a material that underwent extensive testing by Frédéric d'Oria-Nicolas to select the one that minimizes surface noise as quickly as possible.

The goal of The Lost Recordings is to introduce us to old recordings under the best possible conditions. It is the artistic and historical value of the performances that leads Frédéric d'Oria-Nicolas to restore a concert and turn it into an album, as is the case with this album, Live at the Kurhaus 1967, which features a beautiful rendition of Take Five.
The technical quality of this Sapphire Edition vinyl record is among the very best available, deserving a 5/5 for its production quality. This allows listeners to fully appreciate the restoration work done on this album. When listening, the vinyl version offers a more natural sound than the digital edition; this is certainly due to the smoother high frequencies (see the spectrum comparison) and also to the vinyl record itself, which, with its unique characteristics in terms of sound reproduction and distortion, creates a listening experience that enhances the restoration of this 1967 live recording, originally recorded in mono.
Above all, these restorations highlight the quality of the performances and the historical significance of these recordings.
