“A Decade of Double Vanity” arrives at The Bowery Ballroom as a live Rock/Pop event featuring Broncho. The title suggests a retrospective frame, looking back over ten years with the double edge of self-myth and self-critique that runs through pop culture. In a room with its own New York concert history, the set reads as a small-scale document of how bands age in public, with noise and melody competing for the narrative. One clear takeaway is its interest in the passage of time, more than in novelty.
