Re-mastering a classic
Caroline Henderson - Cinemataztic
When Sony Music wanted to re-release this seven times Danish Grammy winning album to celebrate its 20th anniversary, they approached me with the task of carefully restoring and re-mastering the original versions from digital archives.
Due to the helical scan write heads used for DAT this job included procuring several tape players to find a compatible azimuth for an optimum transfer, as well as gentle digital processing and spectral repair.
Jacob Bellens - Trail of Intuition
The 2018 solo album from Jacob Bellens (I Got You On Tape) on HFN Music (Trentemøller, Blaue Blume, Lydmor) was mainly produced by Rune Borup, whose signature sound includes wide and lush analog synths and deep bass.
The songs have Jacob Bellens' voice as the focal point, but also feature prominent drums, so the vinyl masters required full use of the dynamic range, a controlled stereo image and a focused low end.
