Maroon 5’s annual end-of-year shows at Mandalay Bay have become as much of a Las Vegas holiday tradition as countdowns and champagne toasts. The band’s trajectory for the past five years could easily be represented by its New Year’s Eve live sets, if the Dec. 29 concert it played in 2012 as part of the Overexposed Tour counts. Since 2014, the musicians have hit the stage at Mandalay Bay Events Center every Dec. 30-31, indicating all is well in the world of Maroon 5.

More fervent followers witnessed the live debut of “What Lovers Do” from the album Red Pill Blues, which was release in November 2017, at last year’s shows. That song became the opener for the Red Pill Blues Tour, which wrapped in October with two mid-month concerts at Madison Square Garden. Maroon 5 debuted the single version “Girls Like You” from Red Pill Blues at the May 30 opening date in Tacoma of their Red Pill Blues Tour, then watched the collaboration with Cardi B climb the charts through the summer until it spent six weeks at No. 2, then hit No. 1 in September.

In other words, Maroon 5 comes into Las Vegas on top of the world, and at the top of their game. It had been six years since Maroon 5 last hit No. 1 with “One More Night” and 15 years since the band first entered the charts with “Harder to Breathe.” That song is still a staple of Maroon live sets, along with “This Love,” “Misery,” “Animals” and “Moves Like Jagger.” The latter song has been closing out the main sets on the latest tour before the band has been resuming the stage with a cover of Alphaville’s “Forever Young.” Michael Jackson’s “Rock with You” has been making it into the main sets as well.

The Oakland Press summed up Maroon 5’s Sept. 30 concert at Little Caesars Arena as “a full-throttle pop spectacle” that was “lean and refreshingly devoid of shtick,” save for a mirrored ball that dropped during “Rock with You.” Levine strapped on an acoustic guitar during the encore and dedicated “She Will Be Loved” to the late Aretha Franklin before ending with tour closer “Sugar.” The band segued from song to song during a tight 18-song set with guitarist James Valentine playing a “biting solo” during the hard funk workout of “Harder to Breathe.”

With Maroon 5 refreshed after more than two months on break, the New Year’s Eve shows can only benefit from the musical cohesion between band members who spent nearly six months on the road together this year. Hopefully they’ll hold onto that cohesion if they are confirmed for the halftime show slot at Super Bowl LIII in Atlanta. Beyond that, and the likelihood that Adam Levine will still be a coach on reality talent show The Voice for the 16th season, little is available about Maroon 5’s plans or resolutions for 2019, although odds are they’ll be back in Vegas to ring in 2020.
