Although iconic, the Hard Rock can't sustain nostalgia as a business any longer.
Some of us are enthralled seeing a signed guitar from a rock legend and will go and eat and drink at a place that features that sort of thing but today's music is throw away or so far from rock that those who listen to it would never darken a Hard Rock cafe because it's 'not their thing'.
Just look at the ridiculousness around Notorious B.I.G., a criminal turned gangsta rapper who was murdered, inexplicably had a banner raised at Barclays Center, seriously??
That is the type of nostalgia that is hip today, not rock legends.
If the Hard Rock had a shine for Tupac or a signed DJ board & mouse ears from Deadmau5 then maybe they would attract a new audience.
