The Flaming Lips don’t play shows — they put on spectacles. The alt-rockers embrace eccentricity in their live performances: they’ve rolled around in giant spheres, constructed a giant UFO, even dressed concertgoers up in animal costumes and Santa hats and had them dance around onstage. Psychedelic! Their secret show during Austin’s 2006 SXSW (South by Southwest) was no less groovy. The Lips covered Queen’s “Bohemian Rhapsody,” duetted with female rapper Peaches and let two fans get engaged onstage. Well, marriage is supposedto be a trip, right?
