He signed with Sony Music after the competition and released his debut EP, Toulouse, in February.
Brooklyn-based alt rock band American Authors are known for their debut song, Best Day of My Life.
Santa Monica's Grammer was the first male artist to hit the top 10 on Billboard's adult pop chart in America with his first two singles, Keep Your Head Up and Fine by Me.
