Like most electronic artists whose careers have spanned nearly 20 years, Thomas Brinkmann is the consummate experimenter. The newest six tracks by this minimal techno/dub vet have but one agenda: plumbing abstract soundscapes where clicks, noises, and tonal harmonies fuse together in a Vulcan mind-meld of sound and concept. Even if sound-art installations aren’t your thang, Brinkmann’s carefully modulated minimalism (as on “Tilt”) injects some ernst (German for “serious”) into these machine grooves.
