George Strait played country music in high school, but didn’t become serious about it until serving in the U.S. Army in the early ’70s. The native Texan performed with an Army-sponsored band, and after being honorably discharged went to college to study Agriculture. Music kept calling, and Strait fell in with a band that would become the Ace in the Hole Band. He signed his first record deal at age 29 and released ‘Unwound’ as his first single in 1981. Nearly 100 singles later, he holds the record for most No. 1 singles — in fact, only two have failed to crack the Top 20. Strait was inducted into the Country Music Hall of Fame in 2006 and began his retirement from the road in 2013.
