Formed in 2004 by a group of freshmen at the U.S. Air Force Academy in Colorado Springs, CO who—due to the discipline and rigors of their "doolie" year—sang together in the only place they could, "In the Stairwell" is the Academy’s premier all-male a cappella group. Now an official club, the cadets enjoy practicing each week and performing music from contemporary hits to the national anthem for official functions and entertainment on-base and in the community. All members graduate and commission as military officers. 
In The Stairwell's Judge Cuts performance in Episode 1210 consisted of singing NSYNC's "Bye Bye Bye". Guest judge Seal gave the group a standing ovation. The group's performance was strong enough for the judges to send it to the Quarterfinals.
