It was almost too beautiful to bear: Thursday night Fleet Foxes unveiled their expanded lineup and new songs at the intimate Columbia City Theater in Seattle. Announced Wednesday morning, the impromptu show sold out in minutes, allowing three hundred fans a uniquely personal encounter with the city's most beloved young band in the city's finest-sounding room. The historic theater is a former vaudeville hotspot built in 1917, and Thursday night it felt like Seattle's living room with Fleet Foxes as house band. The set was a warm-up for the world tour the Foxes embark on in a few weeks. It was a chance to break in the new instruments, mattress-size mixing desk, and sophisticated in-ear monitors the band will use when playing rooms five times the size of Columbia City Theater.
