Not to be that person, but I saw Vampire Weekend way back when, in 2008, when the Ezra Koenig–led group were on the come-up with the melody-drenched, college-thoughtful, Afropop-infused songwriting of their self-titled debut. Nearly a dozen years and minus one founding member later, they’re touring behind fourth album Father of the Bride, and have sold out the 7,000-seat WaMu. “Harmony Hall” is what they’ve been playing on the radio, but the most obvious standout is the Grateful Dead–vibing first single “Sunflower,” its rising and falling scat singing serving as both the refrain and a surprisingly well-placed rhythmic device. by Leilani Polk
