Considering her penchant for changing the game faster than you can say “meat dress,” one has to assume that Lady Gaga will be completely reinventing her stage show when she heads back out on the road to promote her upcoming album Born This Way.Just in case, though, anybody wantimg to relive the magic of Gaga’s Monster Ball tour can tune into HBO on May 7.Lady Gaga Presents The Monster Ball Tour: At Madison Square Garden was recorded at the venerable arena in her hometown, and not only captures the spectacle of the tour—with its army of dancers, massive stockpile of pyro and at least one giant anglerfish—but also some exclusive behind-the-scenes moments, like this teary backstage breakdown, below:Not to belabor the point, but the preview, with its black and white film and the mid-styling confessional, borrows an awful lot from Truth or Dare, the groundbreaking documentary that captured Madonna on her 1990 Blond Ambition tour.It’s not going to get Gaga away from those pesky comparisons, but if her HBO outing is anywhere near as good as Truth or Dare (which holds up remarkably well, even after 20 years; seriously, Netflix it), then Monster Ball may very well be essential viewing.
