When Perry Farrell introduced Love and Rockets on Saturday night, he announced them as one of his favorite bands of all time. It’s easy to see why Farrell is enthusiastic about the group that formed out of the ashes of Bauhaus: they mix jagged, fringe sounds with deep grooves and huge pop hooks — exactly the type of music Farrell has been chasing his entire career. Frontman Daniel Ash — dressed in a Keith Richards pirate motif — cooed and moaned lyrics about obsession over hot slabs of roaring bass riffs (“No Big Deal”) and pulsating goth rock (“Haunted When the Minutes Drag”). They even made some room for some heavy metal theatrics. It was a nice nod to Lollapalooza’s past, as Love and Rockets are the sort of band that its founder wanted to spread to the masses with his festival in the first place.
