21 Hours started out as an experiment at Carthage College. Lead singer Benjamin Mulwana wanted to play at the Student Spotlight and asked bassist Suresh Graf to join him for the show. While jamming, they thought to ask their friend, and now percussionist, Justin Hall to join them as well. When asked what their band name was at the audition for the Student Spotlight, Suresh chose the name 21 Hours, as they had only been a band for exactly that long.

21 Hours now has so new faces, Jacob Hemenway on bass and Shane Madsen on the drums. Benjamin met Jacob and Shane in the vibrant music scene of Kenosha. With an immediate connection to one another Jacob and Shane came along side Benjamin sharing their talents and love for music.
