In April 2024, Austrian electronic duo HVOB (Anna Müller and Paul Wallner)—whose album Trialogue (2023), with its downtempo electronics and Müller's emotive vocal loops, revived interest in atmospheric techno after a Boiler Room breakthrough—performed at Wiener Konzerthaus, Vienna's legendary hall opened in 1913 as a symbol of Austrian musical heritage with 2,000 seats and acoustics for symphonies and chamber shows. Their 60-minute set on April 20, captured in high quality by ARTE Concert, embodied their European tour climax, where Wallner's throbbing beats intertwined with Müller's vocal improvisations in tracks like "Bones (feat. HVOB)" to evoke meditative resonance before a sold-out crowd. As part of their post-hiatus return, this show highlighted HVOB's role as performers, turning the concert hall into a realm of emotional trance.
