The following description comes from the event organizer.

Seattle's original opera in a bar! Opera On Tap Seattle was founded in 2011 and has since grown to be a highlight of opera in the Seattle area. OOT's mission is to expose new audiences to opera and classical music by taking opera and classical music out of the concert hall and performing it in alternative venues, such as your local pub or dive bar. Roughly once a year, OOT lets their hair down and brings in a program of musical theatre featuring local MT performers alongside your favorites on tap.
