As ratings for NBC's "The Voice" have gone down, two of the TV music competitions celebrity coaches are going back out on the road in the coming months -- and both are headed to Xcel Energy Center.

The St. Paul hockey arena announced a Nov. 18 concert with Usher this morning alongside a March 23 return by Adam Levine's Maroon 5. Tickets for the latter show go on sale first, starting Sept. 13 at 10 a.m. through Ticketmaster and the arena box office at prices yet to be announced. Seats for Usher will open up Sept. 15 at 10 a.m. for $37.50-$152.50.

Following his short-lived tenure as a "Voice" team leader last year, Usher marked his return to the stage at the MTV Video Music Awards two weekends ago, where he performed the new single "She Came to Give It To You." The 35-year-old, Atlanta-reared super-stud – one of R&B's most successful artists of the past two decades -- also posted a new video (posted below) to promote his late-autumn outing, dubbed the UR Experience Tour and set to begin Nov. 1 in Montreal.

Maroon 5 just dropped its fifth album, "V," which has already landed another top 10 hit with the lead single "Maps." Their tour will feature Shakira-affiliated Canadian band Magic! along with one of Levine's non-"Voice" protégés, Rizzo Crane.

Between now and the tour, the M5 singer Levine will run through another season of "The Voice," this time with new coaches Pharrell Williams and Gwen Stefani alongside Levine's returning odd-couple partner Blake Shelton. The new season is scheduled to begin Sept. 22.
