<Progressive> VERTEX is a collaboration project between Nikola Kozic (aka Zyce) and Slobodan Gacesa (aka DJ Merlin); Earth is their second album. This tight progressive release continues in the wake of previous successful acts delivered by TesseractStudio. The tunes are so clean and perfect it can almost be described as clinical, but not in a cold way, just something to be admired and enjoyed. The opening track is yet another collaboration, this time with Solar Kid and the vox is angelic, melody sweet and beats gentle. On Surface the repeated pattern produced on the synth is very hypnotic. I could imagine the white snow and bright sunshine while listening to the clinical but beautiful Avalanche. Welcome to Serbia has a wonderful echo of a jazzy trumpet that periodically appears between the sweet melodies and deep beats. Faith and Enlightenment both have that uplifting sound that awakens the mood to dance. Out of Orbit by Vertex & Vice contains space docking and hissing sounds amongst the cool beats. Northern Lights by Vertex feat. Float is another groovy hypnotic track with nice steady build-ups. The Joy of Silence is an ode to tranquility and closes the album on a perfect note of meditation. Highly recommended.
