An alternative rock band’s finale at the The State Theatre in Portland included an encore song, theatrical smoke — and firefighters.

Officials say the theatrical smoke or fog used by The Pixies set off a smoke alarm Tuesday night, forcing concertgoers to exit the building.

Fire Capt. John Brennan tells the Portland Press Herald that the theater’s doors were opened, the smoke cleared and the alarm was reset.

The show was sold out and the theater can hold more than 1,600 people, but some of the patrons had already left before the band’s final song.

Concertgoer Jeremy DaRos says, “There was never a sense of panic.”
