They are touring in support of their debut album Shrines which will be released July 24. Blue Hawaii is the special guest. 8 p.m. 400 Lincoln Ave., Millvale.
3) The Book of Mormon, unexpurgated, opens tonight. The guys in white shirts and black ties are here, and nooo, they are not your Blues Brothers. They rock the house with a sermon about the secret power of frogs, a bunch of songs you’ll want to sing in the shower (but not around small children, please), and a happy ending that might even make you, um … think. There are still some seats available for this blockbuster Tony and Grammy award-winning play by South Park television show creators Trey Parker and Matt Stone, along with Robert Lopez, who co-wrote Avenue Q. Catch the touring company of The Book of Mormon, through April 7 at the Benedum Center. 7:30 p.m. tonight; various evening and matinée show times. 237 7th St. Cultural District. (By Mike Vargo).
