Los Angeles buzz-band Silversun Pickups had a good reason to cancel their November 2006 appearances in St. Louis: Instead of opening for Aussie rockers Wolfmother at Mississippi Nights or playing its Vintage Vinyl in-store the quartet was taping an appearance on The Late Show with David Letterman. But the fuzzed-out rockers made good on their promise to perform at the Loop landmark the next time they rolled through. In fact, the too-short acoustic set SSPU performed in April before an electric, plugged-in set as the openers for sensitive songwriters Snow Patrol benefited from the anticipation. There was a crackle in the air, feelings of hope, optimism and pure excitement among the sizable crowd which ranged in age from enthusiastic high school students to adults who rushed directly from work. Frontman Brian Aubert talked and joked with audience members with unself-conscious glee after unleashing a few cuss words, he hilariously made a father cover his young son's ears although his cathartic screams had more of a lasting impact. SSPU singles such as "Lazy Eye" and "Well Thought-Out Twinkles" hit rawer emotional nerves when stripped to their skeletal, acoustic forms as if they could start a global revolution, one note at a time.
