Las Vegas wouldn’t be the entertainment capital of the world without, well, entertainment. The shows and performances are coming back. The free (yes, free) concert series at Fremont Street in Downtown Las Vegas returns, with a number of rock acts playing throughout the year. Also, several artists are kicking off new Las Vegas residencies, including, Carrie Underwood, Usher, and Sting, joining long-term residencies from Barry Manilow at the Westgate Las Vegas Resort & Casino and Santana at Mandalay Bay, plus Vegas mainstays like magic and illusionist shows, Cirque du Soleil and comedy. And several major music festivals, such as the iHeart-Radio Music Festival will return beginning this fall.
