MEXICO POPMART???

I was only recently able to listen to the entire mexico popmart show, and it
left me wondering why this is the show rumoured to be commercially
released?? I did not feel that the band's performance was at all superior to
any other show, and I actually found it to be lacking 'feeling' compared to
other popmart shows....I appreciate that the crowd was incredible and
supported the band throughout the entire show, but their performance was
just not 'there'. So is anybody able to enlighten me why this show is
rumoured to be the official popmart release? Thanks in advance.
