McComas was born in Bethesda, Maryland; his family moved to Harrison, Arkansas when he was four years old. At age sixteen, he attended a Paul Overstreet concert; while at the concert, Overstreet gave McComas the address of his publishing company. McComas submitted a demo tape to the publishing company, who then encouraged him to continue working on his writing skills.

McComas later attended college, but soon dropped out to move to Nashville, Tennessee. McComas briefly signed to Mercury Records, before he landed a deal with Lyric Street in 2001, charting the singles "Night Disappear With You" and "I Could Never Love You Enough". In 2003, he landed his first Top 10, "99.9% Sure (I've Never Been Here Before)" and the follow up "You're in My Head", a #21 hit on the country charts. Another single for Lyric Street, "The Middle of Nowhere", fell short of the Top 40, and Lyric Street dropped him not long afterward. He later signed to Katapult Records, where he released Back Up Again, his second album.
