As part of "Durchlüften"—a free summer concert series held for the past five years in the Humboldt Forum’s Schlüterhof—Uche Yara, an Austrian artist based in Berlin with Nigerian roots, presents her latest power-rock songs; she is known, among other things, for an *Arte Tracks* profile and a celebrated performance at the RadioEins Parkfest. Charlotte Colace opens the event with the mellower sounds of vintage soul.
