Exactly 31 years later, Roger Waters arrived at the Staples Center in Los Angeles to perform a re-imagined version of “The Wall,” as part of a worldwide tour celebrating this monumental concept piece. Although there was no involvement of anybody else from Pink Floyd, this was the ultimate staging of the masterpiece, packed with over-the-top visuals, soul-stirring musical bliss, and powerful statements. For the 20,000 people in attendance, it may have been a pricy ticket, but in return they received an unparalleled live experience for the eyes, ears, and mind.
