You won’t forget this lady’s Haus party

The last time we saw Lady Gaga perform inDallas was at the Round-Up when she was another club singer finding her audience. And boy did she. She comes back arena-style, selling out large venues, and the gays have followed her through to superstar status. For two nights, AAC becomes the Haus of Gaga.

DEETS: American Airlines Center, 2500 Victory Ave. July 22–23. 8 p.m. $49–$175.
