The actor/musician brother duo of Nat and Alex Wolff, FKA The Naked Brothers Band, derived their music from a  Nickelodeon show that the brothers starred in earlier in their lives.

The pair are currently on tour with Billie Eilish for her Hit Me Hard and Soft Tour for a string of dates including the two-night stand in Chicago. Coming from a different generation, I wasn’t too entirely familiar with their music, but was equally excited to see what the Brothers Wolff had to offer knowing that artists put in the effort to choose their openers— I figured Billie had her reasons. I’m grateful for the phrase “ a picture is worth a thousand words” because I feel like my photos captured tens of thousands of words encapsulating the amount of entertainment to duo emitted in just the short time allotted for an opening act.

The United Center is definitely no small feat to conquer as an opener and I’ve seen many solid openers in the past not make the mark or hold the crowd’s attention, and that wasn’t the case for last night’s performance. That had a commanding presence and easily connected with the crowd, who let’s face It we know had only Billie on their minds. Some of the fans had even been camping out since Sunday and others were still in their tents on a cold rainy Chicago night for their line spot in the  morning for tonight’s show. Nonetheless, both Nat and Alex held nothing back and showcased how they’re  not only brothers or actors, but also rockstars.
