Add country stars Old Dominion and Kelsea Ballerini to the impressive list of guests appearing on Songland, a new reality TV show slated to debut this spring on NBC. They join songwriter and Episode 1 guest Shane McAnally as Nashville's confirmed contributors to the series.

While most TV singing competitions target would-be stars, Songland -- an 11-episode spin-off of The Voice -- seeks songwriters interested in providing established names with the songs that make the whole world sing. Per the series' teaser trailer, aspiring songwriters will demo their compositions on-air for stars including Ballerini, Old Dominion, Charlie Puth, the Jonas Brothers, Meghan Trainor, Will.I.Am, Leona Lewis, Macklemore, Aloe Blacc and more.

"We're going to pull back the curtains, and we're going to show you how music is made," says OneRepublic's Ryan Tedder during the show's one-minute teaser trailer. Tedder serves as an executive producer alongside The Voice's Audrey Morrissey, director Ivan Dudynsky, the Eurythmics' Dave Stewart and the show's host, Maroon 5's Adam Levine.

Competing songwriters -- five each week -- will be mentored by three music producers, with a rotating cast of guests filling those spots each episode. Three writers will move from the audition panel to the studio, paired with a producer, and each week's winning writer will have their song recorded and released by the week's artist judge.

Songland will premiere on May 28. The show will air on Tuesdays at 10PM ET.
