Jesper and cousin John Dahlback don’t push things nearly as hard, but they do get the acid just right, notably on Naslund’s “Final Trip,” a delectable slice of underground resistance. Also of techno note: Juan Atkins’ appropriately titled “Rebound” EP (on Bone’s Subject Detroit imprint) lives up to its name in fine style, especially on the rubbery glissando of the title track.
