Mikkel Meldgaard has been flirting with dubby studio effects since 2000, notably dropping several releases on Kompakt. Yet Peaks and Troughs finds the Danish producer known as Mikkel Metal tumbling into darker and murkier territory, with mighty fine results. Metal gets assistance from the increasingly gravel-voiced (and perhaps slightly overused but still brilliant) Paul St. Hillaire, who is featured on four of the albums best tracks (“Jeman,” “Never Run Away,” “Visions of Life,” and “Get Over”). On the instrumentals “Who-Man” and “Frico,” Metal really powers up the rhythm machine, building epic soundscapes and crushing basslines at the same time.
