The night that Tigerface crashed its own party might've been the kind of mortifying experience that most musicians would rather forget, but no matter. We were damn impressed. It was a sticky July evening at Modified Arts, and the Scottsdale quartet was in the middle of its opening set for psychedelic D.C. band Weird War. The steadily swelling crowd was mesmerized by Tigerface's Faint-inspired grooves and dark, Nine Inch Nails-worthy intensity. But we never saw Trent Reznor do a stage dive with an instrument to keep a song going, which is just what keyboardist Ari did when his synth stand fell forward into the audience. Remarkably, the show did go on; instead of missing a beat, the other band members kept rocking as Ari caught the keyboard in midair and continued to play chords, sprawled out on the floor on his stomach. Talk about dedication. It might take a bigger budget for Band-Aids (or a good set of elbow pads), but maybe Tigerface should make this feat part of its regular act.
