Despite their demanding schedule, these 15 cadets at the US Air Force Academy still find time to practice as a group.

Known as Stairwell, the band earned their name from practicing on the stairwells of the academy due to the lack of rehearsal space.

Their performances are nothing short of impressive, captivating both judges and audiences alike with their impeccable synchronization and stage presence.

After each performance, they receive a standing ovation, leaving even the judges and audience members like Mel feeling emotional.

Enjoy their rendition of “Castle on the Hill” by Ed Sheeran.
