Most bands spend their entire careers building a repertoire deep enough to compel an arena’s worth of fans to sing along to every lyric of their well-rehearsed, choreographed 90-minute show. Phish, who just completed a high-profile, high-stakes, nine-night residency at Sphere in Las Vegas, took it to another level without a single song repeating over the entire three-weekend affair. In total, the band played for upwards of 27 hours.
