This time around, the New York group had no problem packing two shows at Red Rocks Amphitheatre, which holds about 9,400 people per night. Using that alone as a gauge for Fun's success, the band has officially blown up.
For all the flamboyant gloss that Fun tends to bring to their music, singer Nate Ruess has a chaotic motor in him that would put most punk rock singers to shame. After a brief, opera-inspired opening number, the man essentially ran laps for the next three songs, barely planting his feet long enough to occasionally pump his fist in the air. If Ruess isn't actually having, well, fun, he deserves an Oscar for his acting during the past several years.
Earlier, maligned/beloved indie duo Tegan and Sara showed off some surprisingly catchy, synthy style. But after a solid hour, it was hard not to notice that, as striking as their musical formula may be, they rarely deviate from it.
