Arcade Fire's Epic Conclusion

While the Soundgarden grunge revival was happening to the south, Montreal's Arcade Fire was enrapturing ears on the north field of Grant Park with swelling, swooning indie-pop anthems. Tunes from the band's latest album 'The Suburbs' were greeting enthusiastically, but the crowd sang the wordless refrains of older hits like "Rebellion" and "Wake Up" with an almost religious, unifying zeal. The vibe was so thick when the lights came up, that after three days of non-stop heat and endless port-a-potty lines, no one wanted to leave the grounds. This, ladies and gentlemen, is how you end a festival.
