The tour will kick off in St. Louis and wrap up in San Diego on Oct. 5.
"I think the live outdoor kind of summer vibe is always different than the indoor arena tour because there's less emphasis on production and more on live music," frontman Adam Levine said in an interview. "It's kind of the purist form of a tour 'cause there's not too many bells and whistles."
The "The Voice" host added that the band is working on a follow up album to their critically acclaimed record "Overexposed," which according to guitarist James Valentine, "may be a little darker."
"The stuff we're working on now, it definitely has gone maybe a little darker in its sound, maybe back a little bit more to what we kind of did on (our debut) 'Songs About Jane,'" he said.
