JAY-Z paid homage to the late Chester Bennington Saturday by performing "Numb" at a UK concert.

JAY and Linkin Park have history ... they re-did the band's hit "Numb" back in 2004, so the mogul had reason to pick that song out to honor his good friend, who committed suicide a month ago today.

HONORING CHESTER

You hear JAY at the VFest event fire an order to the crowd, "Let's show some love for Chester tonight!"

JAY is in the middle of a heavy touring schedule promoting his new album, "4:44."
