— The Jonas Brothers sure have a lot of friends in the music business. They’ve been inviting a surprisingly deep array of guests to the stage at each concert on this tour. The list has included Demi Lovato, John Legend, Kelsea Ballerini, Machine Gun Kelly, Hanson, 5 Seconds of Summer, Jason Mraz, Alessia Cara, Plain White T’s, Dashboard Confessional, Russell Dickerson, Jordin Sparks and Natasha Bedingfield.
In St. Paul, the trio was joined by distinguished Twin Cities musicians who aren’t necessarily nationally known. It was mostly the players who accompanied Nick Jonas on his 2010 side project, Nick Jonas & the Administration — namely keyboardist Tommy Barbarella, guitarists Sonny Thompson and Cory Wong, and bassist John Fields, who produced the Jonas Brothers’ second and third albums.
The Administration’s heavier rock sound diverged from the usual pop-rock sound of the Jonas Brothers. However, four songs might have been a bit indulgent, though the funk-rock of “State of Emergency” packed a memorable punch.
