You know who Rivers Cuomo is, right? He's the supposedly awkward and reluctant Weezer front man who writes nerdy guitar pop in his bedroom, never does interviews and only plays shows when he has to.
Apparently not. Just three songs into Weezer's Vector Arena show, Cuomo jumped from the stage, ran to the back of the venue, climbed on top of a small corner bar and screamed the chorus to Troublemaker - "I'm a troublemaker, never been a faker" - while pouring beer over fans.
It was a brave early move that ignited an otherwise sluggish start and helped smash all those shy stereotypes that have built up around Cuomo and the Los Angeles-based group over the years.
And with this being a "memories concert" - a dozen or so greatest hits, followed by the self-titled "Blue Album" in full - it provided a major surprise in a show that didn't really promise any surprises at all.
The real shock was just how good Weezer were, considering their last concert in New Zealand was the infamously awful Pinkerton show at the Logan Campbell Centre in 1996, from which fans and the band reportedly couldn't escape fast enough.
