Red Hot Chili Peppers drummer Chad Smith (not to be confused with Will Ferrell) is a beast behind the drum kit. During his band's headlining shows in the UK, the band had Japanese teen metal sensation Babymetal open the gigs.
At the O2 Arena on December 18, Chad joined the band for an awesome cover of Judas Priest's "Painkiller" and "Breaking the Law," tracks Babymetal covered with the metal God, Rob Halford, himself. Watch that footage here. After the performance, Chad surprised Su-metal with a birthday cake, as it was her 19th birthday.
