In February 2017, British post-punk band IDLES—at the early career stage post their debut album Brutalism (2017), marking a breakthrough with raw, aggressive sound and lyrics on class struggle—performed for Rockpalast, WDR's legendary series launched in 1974 as a platform for live indie and alternative broadcasts. Their 30-minute set, recorded at Gebäude 9 in Cologne before a small audience, embodied their first European tour climax, where Lee Kiernan's chaotic riffs merged with Joe Talbot's emotive delivery to evoke resonance among listeners. Featuring tracks like "Colossus" and "1049 Gotho", this show highlighted IDLES' role as British post-punk innovators, turning the studio into a realm of collective unity.
