5.1 Mixing News and Reviews


Anthony Phillips – ‘1984’


5.1 Surround Mix and Mastering


Esoteric | ECLEC 32550


Goldmine Magazine – 2016


And so it continues, this painstaking and glorious remastering of the Anthony Phillips back catalog, album-by-album, out-take-by-out-take, and all beautifully bolstered with 5.1 mixes that truly rank among that particular art form’s crowning achievements.


… it’s fascinating to slip from the parent album to the bonus-stacked second disc, and catch the piece in an earlier mix – and then leap from that to disc three’s 5.1 mix, which has to be experienced to be believed…


Anthony Phillips – ‘Sides’


5.1 Surround Mix and Mastering


Esoteric | ECLEC 52510


Record Collector Magazine – 2016


…Superbly packaged, with a craftsman’s care, this four-disc edition has a great 5.1 mix from Simon Heyworth & Andy Miles. Sides remains a great snapshot of Phillips sharpening up, like so many of his peers, in the backwash of punk.
