TheRockRetrospective on Instagram: "Led Zeppelin, “No Quarter” (Live at the O2 Arena, 2007). Performed at the Ahmet Ertegun Tribute Concert in London, this 2007 reunion saw Led Zeppelin revive one of their most mysterious and hypnotic tracks. With John Paul Jones’s swirling keys, Jimmy Page’s moody guitar work, and Robert Plant in full command, “No Quarter” became a masterclass in tension and atmosphere — proof that their chemistry hadn’t faded one bit."
