Day two of Lollapalooza got off to a smashing success. Metallica bass player Robert Trujillo surprised patrons at Perry Ferrell’s Kids’ Tent with an impromptu jam. No wonder, Trujillo’s son, Tye, plays bass for the band The Helmets, who just happened to be on the Kidzapalooza stage today. Trujillo was watching like a proud pops from the side stage before going on with Perry. Ferrell and Trujillo then rocked on to the delight of the very surprised crowd. James Hatfield and the rest of Metallica were in the audience to catch The Helmets’ set.
