The Flaming Lips roll into the Agora tonight as part of a tour that will feature a special performance of their 2002 album Yoshimi Battles the Pink Robots to mark the 20th anniversary of its release. These concerts are highly visual and festive affairs that show the extent to which frontman Wayne Coyne has become a modern-day hippie who eschews good vibes and feel-good energy. The concert begins at 7:30.
