In June 2019, German indie-rock band Giant Rooks—from Westphalia and formed in 2014 as a student project influenced by Tame Impala and The Strokes—whose debut album Rookery (2019), with its psychedelic textures and lyrics on everyday alienation, broke Germany's charts—performed at Puls Open Air, an annual festival at Kaltenberg Castle, Bavaria, launched in 2019 as a platform for indie and alternative music emphasizing local talent among 20,000 attendees. Their 40-minute set, captured in high quality, embodied their nascent breakthrough era, where Fred Ritter's garage riffs merged with synthesizer improvisations to evoke warm resonance under summer sun. As part of their first major tour, this show highlighted Giant Rooks' role as German indie innovators, turning the Bavarian castle into a realm of collective trance.
