Tegan and Sara Quin, the Canadian identical twin sisters who perform under the name Tegan and Sara, return to Dallas for a concert at Annette Strauss Artist Square next to the Winspear Opera House on Oct. 11 at 8 p.m. Tickets for the show, which features opening act Speak, go on sale at ATTPAC.org at 10 a.m. Friday.

We interviewed the sisters, who are also both lesbian, a few years ago in Dallas Voice. Their latest CD, also a DVD, is 2011’s Get Along.
