Getting your Trinity Audio player ready...
Katy Perry and Lady GaGa (below) have more in common than retro fashion sense and the honor of a Grammy nomination. They both are performing sold-out shows at the House of Blues (329 N. Dearborn St.) next week. We have a couple ideas that may score you a ticket.
Call: Ticketmaster (312-559-1212) or the House of Blues box office (312-923-2000) every day — even the day of the show. A limited number of tickets are sometimes released.
Go alone: Retail ticket outlets such as Carson Pirie Scott sometimes have single tickets available.
Katy Perry performs 6:30 p.m. Thursday. Tickets are $16. Lady GaGa performs at 6 and 10:30 p.m. Tuesday. Tickets are $22. TRIBUNE
