A man behind me initially responded "Huh?" as the song started and concluded "Whoa" once it finished. I agree. By the third song into the set, Xiu Xiu unleashed their newest club banger, 'Wondering,' a song that has actually achieved the oft-threatened merger of Stewart's hysterical femme vocals, skewed pop sensibility, dance beats, and screeching noise into something that more than, say, 10,000 people would be into. It provoked much dancing from a crowd that was also ready to mosh as they did during the title track off "Forget," 'I Luv Abortion,' and a cover of ZZ Top's 'Sharp Dressed Man.' As with the best Xiu Xiu covers, 'Sharp Dressed Man' was warped while Jamie Stewart's warbling inflection emphasized the ugliness of rape culture embedded in the classic rock radio staple.
