Stray Kids kicked off their sold-out 2nd World Tour Maniac arena tour with back-to-back shows this week.

On Tuesday (June 28) and Wednesday (June 29), the K-pop group held two respective sold-out concerts at the Prudential Center in Newark, N.J.

Members Bang Chan, Lee Know, Changbin, Hyunjin, Han, Felix, Seungmin and I.N performed their hits including "MANIAC," "Red Lights," “Back Door” and “God’s Menu."

Fans couldn't get enough of their electrifying dance moves paired with awe-inspiring visuals, such as the group's larger-than-life video panel. Each night, fan chants erupted throughout the entire arena.

A standout moment took place when the group covered Westlife's "My Love," while another memorable moment happened when they split into two groups to perform songs of their choice live on the spot.
