As Drexciya's albums go on they grow in maturity. 'Grava 4' is no different. Yes there are some hard, four to the floor tracks on here, but more and more as you listen to this album, you get the feeling that you are listening to much more than your standard electronic artist, you are listening to an electronic music genius, and that's exactly what Drexciya are, genius. The tinkling electronics, flickering analogs and Detroit strings swoosh around. These guys don't just go into the studio to knock out another album for the sake of it. It's clear time has been taken to craft this album. For this reason, it's an even more amazing album. The sheer class on this album does not diminish, despite the high rate of output from Drexciya. With most acts, the more that is released, the less the quality and the more spread out it is. This is not true for Drexciya. If anyone wants to hear real Detroit Techno at its most creative, emotional and raw, then give this a go.
