On September 4, 2014, it was announced that Jamison would compete in Season 7 of The Voice. During his Blind Audition, Jamison covered John Mayer’s “Gravity”. All four coaches (Adam Levine, Gwen Stefani, Blake Shelton and Pharrell Williams) turned around. Jamison chose Adam Levine as his coach. At the Battle rounds, Jamison faced Jonathan Wyndham, where they sang “Young Girls”. Jamison was then chosen over Wyndham, and in the process advanced to the Knockout rounds. During the Knockouts, Jamison covered “(Sittin’ On) The Dock of the Bay”, defeating his opponent (Blessing Offor) and advancing to the Live Playoffs. During the Playoffs he covered Ed Sheeran’s “Don’t” and advanced to the Live shows, after being saved by Adam Levine. The following week, he sang Nick Jonas’s “Jealous” and was saved by public voting. In top 10 he performed “Uptown Funk” by Mark Ronson and was saved by America’s voting. Top 8 saw Jamison in the bottom four after he covered Marvin Gaye’s “Sexual Healing”. For his last chance performance, he sang “Georgia on My Mind” and was instantly saved by Twitter. In the top 5 Live shows, Jamison covered “Sugar” by Maroon 5 and “When I Was Your Man” by Bruno Mars and was voted through to the finale.
