Given his productivity and the reliability of his release schedule, we were a little surprised to find that "Dawn Chorus" is actually Boris Bunnik's first Conforce album for two years. It's every bit as impressive and alluring as its predecessors, with the Dutch producer wrapping a variety of 6am sounds - frosty chords, dew-laden melodies, sunrise-ready motifs and bleary-eyed riffs - around crunchy and largely weighty beats. These are rooted in classic electro, techno and IDM, offering both titanium-clad heaviness and loose-limbed dancefloor flexibility. Highlights come thick and fast throughout, from the grumpy dub techno flex of "Marooned" and "Incunabula"-era Autechre vibes of "Solstice", to the buzzing, early morning insanity of "Umbra".
