Pink Floyd concerts aren't just gigs—they're fully immersive events. “Careful With That Axe, Eugene” is organ-droning space rock at its most experimental. The extended “Shine On You Crazy Diamond” serves as a showcase for guitarist David Gilmour's weeping lyricism. The thumping “Run Like Hell", one of their biggest productions, is tailor-made for the arena tours they undertook post-The Wall.
