Deftones Hardcore Tribute to Kris Kross



Turns out ... the Deftones were big Kris Kross fans -- and last night, the hard rock band paid tribute to the memory of Chris Kelly with a hardcore tribute at their concert in St. Louis.

The band fused their hit, "Engine No.9" with "Jump" ... and the crowd went nuts.

Uh huh. Uh huh.
