Officials at the new Mosaic Stadium are all smiles the morning after hosting their first big concert.

Guns N’ Roses rocked Evraz Place for more than three hours last night to mainly positive reviews.

Organizers say the experience was "overwhelmingly positive", with everything going off without a hitch.

It was also the first concert at the stadium since the city’s smoking bylaw was passed back in July.

There were a few incidents of people smoking in the building during the concert. Security was going around making them put their cigarettes out, though it became more difficult to find smokers once it became dark.

While post-mortem meetings are still taking place, organizers do not anticipate making any changes for future concerts.
