Your 5 best bets for Vegas entertainment in the week ahead

Pentatonix

Are you surprised to see an a cappella group that came up doing cover tunes headline an arena? Locals shouldn’t be. Las Vegas has hosted Pentatonix four times, charting the gradual ascent of the young power singers from the Hard Rock Live club in 2012 to Saturday’s concert at the Mandalay Bay Events Center (where the quintet was Kelly Clarkson’s opening act last August). Tickets for the 8 p.m. show are $35-$85; call 800-745-3000.

24/7 Comedyfest

A perk of Las Vegas living is the opportunity to see this whole bill of comedians separately. But it’s also the thing that makes it rare to see them all in one Orleans Arena show. The 24/7 Comedyfest on Saturday promises Billy Gardell from “Mike and Molly,” comedic “Pitbull” Bobby Slayton, impressionist Frank Caliendo, former Howard Stern sidekick Jackie “The Joke Man” Martling and more. Tickets are $40-$65 for the 7:30 p.m. show. Call 702-284-7777.

Rita Rudner

The wonderful contradiction of Rita Rudner is the way she says something — in that soft, lovely voice — compared to the things she says: Mildly acidic observations on our consumer habits, relationships and even our general appearance. The veteran of the Strip ventures into the suburbs for 8 p.m. Friday and Saturday shows in the Rocks Lounge at Red Rock Resort. Tickets are $34-$44; call 800-745-3000.

Clint Holmes

If you live somewhere between the M Resort and The Smith Center, don’t let your car head north to see Clint Holmes this time. The local favorite steps beyond his Cabaret Jazz berth to the M Pavilion, where he cranks it up with the 10-piece Santa Fe and the Fat City Horns at 7 p.m. Saturday. Tickets are $25.99-$35.99; call 800-745-3000.

Frankie Moreno: ‘Under the Influence’

Another local favorite, Frankie Moreno, relaunches Saturday in a new casino home, Planet Hollywood, with a new show connecting the dots between his original songwriting and the songs that inspired them. The piano-pounding showman plays at 9 p.m. Saturday with more shows Sunday and Tuesday through Thursday. Tickets are $42-$97; call 800-745-3000.
