Kendrick Lamar's DAMN. Tour made its way to Boston on Saturday (July 22) and featured special guest, Travis Scott dedicating a performance of the song, "90210" to his late longtime bodyguard, Big Tony.

Scott continues his performances from atop a giant bird. This one turned a little somber. In the middle of the set, the Texas rapper explains why his heart is hurting. "Everybody put a cell phone light up in the air for Tony," he tells the crowd. "He was one of the most humble, courageous people of all time. I wanna dedicate this song to this nigga right here, man. Let's do it."

He then launched into the song, "90210." The normally super-turnt Scott ends up rapping the track while sitting down in what was described by one concertgoer as an "intense, teary eyed performance."

It is still unclear how Big Tony passed. Scott first addressed the death on social media yesterday (July 21), posting a series of black and white photos in Tony's memory on Instagram. “U gon be my guardian angel for life bro. I love u mannnnnnnnnnnnn I want u to know that. We all do broooooooooooooooooooooooooo I’m hurt Rest In Peace To my dawg big Tony,” he captioned one photo of them walking together.

“We wouldn’t mob with out your lead. Rip my dawg,” La Flame captioned another picture.
