3.Man Behind the Mask

3/12

The best thing about playing in makeup and costume? Half the arena probably didn’t realize that was Tommy Thayer (right) playing guitar, not the departed Ace Frehley.

4.Porno for Pyros!

4/12

As a nod to their advancing age, co-founders Gene Simmons (left) and Paul Stanley (right) toned down the pyro and lights. Nah, just foolin.’

5.Motor City Love

5/12

Paul Stanley has always been famous for his thoughtful stage banter and the bittersweet Cobo farewell made the 57-year-old lead singer wax nostalgic, telling the crowd…:

6.Playing to the Ladies

6/12

"You’ve always opened your arms and opened your legs for us."

7.Blood Bath

7/12

Those who wondered if there will be regurgitated blood did not go home disappointed: Simmons, 60, did his thing and painted the town red.

8.Groupies Never Die

8/12

Now when girls throw their bras at Paul Stanley (left), it’s not a flirtation, it’s a recommendation.

9.Tongue Kiss

9/12

If that codpiece could talk…it’d probably say far less than Simmons himself has through the years.

10.Kiss Off!

10/12

In addition to Thayer, Eric Singer—not Peter Criss—played drums. He didn’t do "Beth."

11.Rock and Roll All Night!

11/12

Simmons and Stanley tried to outdo one another all night, each playing to the crowd and adding more theatrics.

12.Goodnight Detroit!

12/12

KISS ended the evening, naturally, with a spirited “Detroit Rock City.” Their first album in 11 years, Sonic Boom, comes out next month.
