'Valhalla' opens Hidden Empire's Alexandria EP with a dynamic yet apprehensive approach, as a relentless bassline gradually unfolds along convoluted synths. Stand out track 'Alexandria' captivates from the get-go with its subdued bassline supporting a spellbinding melody, timely accented by spacious pads. What makes it so captivating is the subtle sense of dynamics and keen manipulation of energy, a common trait encountered on all the tracks in this release. Hazy groover 'Sierra' follows in the same vein, shifting energy through assorted sequences varying in dynamics and layers. Meanwhile, 'Odessa' is a straightforward, unapologetically monumental slice with big breakdowns centring on triumphant synths, closing out the soundscape in a grandiose fashion.
