... and to mark the occasion, the New York Times published a meandering but not un-interesting piece about Paul, stadium rock, and baseball.
In a way the Beatles and stadium rock stumbled into each other unprepared. The Beatles, at the time, were using amplifiers less powerful than those in most people’s living room stereo systems today. And stadium public-address systems were designed for announcements and a bit of organ music, not for the pounding beat and rich instrumental textures of a rock band. Not that it mattered in the Beatles’ case: all that could be heard was the shrill roar of 56,000 screeching fans, and better amplification would hardly have helped. But a great deal of technical innovation was required before stadium shows could be regarded as anything like artistic experiences, let alone the gargantuan, carefully choreographed audio-video productions they are today.
