This is too fun! Infectious Grooves, featuring Mike Muir from Suicidal Tendencies, Brooks Wackerman from Avenged Sevenfold and Robert Trujillo of Metallica played a music festival in San Paulo, Brazil and had Jim Martin of Faith No More with them, and decided to rip into a cover of FNM's "We Care A Lot."
If you've never listened to Infectious before, check out this tune from 1994, "Violent And Funky." And get a load of a young Robert Trujillo ripping it up on bass!
