Indie folk heroes Bon Iver have announced additional dates for their spring tour leading up to the Bonnaroo Music & Arts Festival in June. The Justin Vernon-led band will head out to Tulsa, Okla., before spending multiple nights in Florida and down South.

The Grammy winners will be in Tulsa on June 2, Little Rock, Ariz., the following night, and then a three-day stint in Orlando, Miami and Tampa, Fla., June 5-7, respectively. See the new dates below.

Paste Magazine reports that tickets go on sale starting this Friday, April 6, at 10AM ET. The additional dates bolster an already extensive spring tour for Bon Iver, which kicks off April 12 at The Joint in Las Vegas, Nev. The group will then head to Indio, Calif., for the first of two weekend sets at the Coachella Valley Music and Arts Festival on April 14.

In related news, Bon Iver have teamed up with Flaming Lips for a song to be included on a Record Store Day-exclusive double album. The track, which is entitled 'Ashes in the Air,' can be heard here. Other guests who appear on the Flaming Lips collection include Chris Martin of Coldplay, Nick Cave, Ke$ha and more.
