Tegan and Sara are set to perform at the Aragon Ballroom next March and tickets go on sale Friday.
The Canadian duo, now a full band, will be making another appearance in Chicago early next year. The sisters, who also happen to be lesbians, have been touring the country - and the world - extensively for the past few years and are at it again.
Their latest album, Sainthood, is set to be released later this month along with a three-volume book to accompany the album.
