Pink Floyd are commonly recognized as a band without a frontman that attracts the attentions of the crowd: among the natural effect of this, the band, as their success grew, needed to reluctantly change their concerts venues, forgetting those small places where silence was almost religious and playing music was a different kind of experience.
The Wall is published at the end of 1979, after a decade where we saw Pink Floyd rising at the top of the global success: the album is their most complex and challenging work and will mark the end of the band, that will implode few years later.
