Who could be in a better position to understand <a href="https://okmagazine.com/search/joaquin" target="_blank"><strong>Joaquin Phoenix</strong></a> than <a href="https://okmagazine.com/search/casey" target="_blank"><strong>Casey Affleck</strong></a>? They’re both the younger brothers of superstars — Casey’s big bro <a href="https://okmagazine.com/search/affleck" target="_blank"><strong>Ben Affleck</strong></a> and Joaquin’s revered late sibling River Phoenix — who have managed to step out of the shadows and earn accolades of their own.

And what better way for Casey to begin his new career as a director than to make a documentary about Joaquin, who recently retired from acting (or so he says) to focus on making music?

So that was the scene on Friday night at club LAVO inside The Palazzo in Las Vegas, where a barely recognizable Joaquin, who surprised many with his singing chops when he portrayed Johnny Cash in Walk the Line, stepped on stage before a curious crowd and in front of Casey’s cameras.

Before the show, the Gladiator star enjoyed a specially prepared vegan meal in LAVO’s private dining room.

Later, after a bit of beer at the bar while listening to the sounds of DJ Five, Phoenix took to the stage for a brief three-song set during which he stopped only to light a cigarette and take a quick swig of a cold beverage.

After he finished performing, Joaquin accidentally tripped leaving the stage and slid down the banquette. According to witnesses, he celebrated by "dancing around and jumping up and down so hard his beanie flew off."
