McKagan hit the stage with Slash at the city's Mandarine Park to play "It's So Easy" as the first encore before they were joined by Clarke for the show-closer, "Paradise City."

It was the second night in a row for McKagan, as he teamed with Slash for the same pair of tunes on March 6 at Teatro Vorterix. Both concerts saw Duff McKagan's Loaded and Clarke open for their former Guns N' Roses bandmate.

"Its been an amazing couple of days," says Slash. "SO much love from Argentina fans; + jamming w/ @DuffMckagan & @GilbyClarke Good X's THANK YOU!"
