There was no shortage of memorable concerts over the past year, with shows ranging from Lady Gaga at the Pepsi Center to LCD Soundsystem at the Fillmore to Gorillaz at Wells Fargo. But none were quite as memorable as this one. Three decades after Pink Floyd first conceived this production, technology finally caught up to the original vision, and Roger Waters brought the whole spectacle to life with flawless precision. From the opening explosions of "In the Flesh," complete with a WWII-era biplane dive-bombing the partially erected wall, to the closing notes of "Outside the Wall," the evening was positively mesmerizing. The sound wasn't just good — it was an expansive, enthralling, spectral, three-dimensional experience. Combined with the stunning visuals, pyrotechnics, inflatable creatures and airborne pig, it was like watching a digitally remastered version of The Wall in 5.1 surround with thousands of your friends.
