Substak is the work of Kostas Staikos, who hails from Athens, Greece. I have reviewed several of his releases on Inner Demons, and they all have different feels, so it is interesting to see what he has each time. The liner notes state that “Nexus Ep focuses on darkness not as a destination, but as the constant environment through which light must travel.” Sounds interesting, so let’s step into the shadows and see what we find.

This album opens with “Morning's Edge,” which is some mellow drone with a light hi-hat cymbal beat throughout. Rather peaceful. If the idea is to evoke the idea of a sunrise, this seems like a good representation. “Chasing Shadows” keeps the drone going, but with a slightly less peaceful feel. “Perpetual Dawn” closes it out with pulsing drone with some sweeping noises thrown in for good measure. This is the most interesting track on the album.

The entire album seems to be an exercise in drone, which works nice as background music. If there is a criticism to be had here, it's that they are similar and I would have liked to see it developed a bit more. On the other hand, they are short enough to enjoy without wearing out their welcome. If you like drone, this would be up your alley. This album weighs in at around 9 minutes.
