Loyola alumnus David Castillo, ’10, teamed up with his friends Arnold Geis, Kevin Blickfeldt and DeMar Neal to form a vocal quartet known as Vox, and together made their operatic debut on America’s Got Talent earlier this summer.

The four artists walked away from their first audition with four “yes’s” from each celebrity judge. They will compete for the grand prize of one million dollars and a headlining Vegas show later in the season.
