On Sunday March 30th, the legendary German guitarist Michael Rother headlines Outline, playing music from the two groups he is most known for: Neu! and Harmonia. The former was his landmark venture into hypnotic, “motorik” music following a brief stint as one of the founding members of Kraftwerk. The latter was a revered collaboration with German experimental/ambient pioneers Cluster. Each of these projects reshaped rock into a bold new framework: hypnotic and mercurial, fusing the spaciousness of dub with a lean, pared-back palette that mirrored the minimalist compositions of Philip Glass and Steve Reich, the conceptual provocations of Fluxus and the taut rigor of proto-punk. Rother’s vast discography is a treasure trove of irreplaceable, flowing avant-rock that has influenced generations without ever having been replicated. The same could be said of Thurston Moore. The former Sonic Youth frontman joins, fresh off the release of his new album “Flow Critical Lucidity.” He’s leading an ensemble alongside Australia’s narcotic pop duo HTRK and Japanese experimental songwriter and highly respected film composer Eiko Ishibashi.
