Heralded as "The Father of Contemporary A Cappella," (Entertainment Weekly), Deke Sharon is responsible for the current sound of modern a cappella, having created the dense vocal-instrumental sound in college, subsequently spreading it around the world.

He has produced dozens of award winning a cappella albums (including Straight No Chaser, Committed, Nota, Street Corner Symphony and the Tufts Beelzebubs), created a cappella groups for Disneyland and Disneyworld, and frequently tours the world teaching students and professional singers.

The hOWLers
Emily E. Shinkle
In the fifth grade, in an attempt to get out of performing at a piano recital, Emily Shinkle had her neighbor break her wrist. It was painful; she had to wear a cast for six weeks. This fiery intensity eventually grew into her love for music, fueling the passion that she has when she comes into her classroom each day to work with her singers. In her eleventh year at The Athenian School, it is in her work with The hOWLers that she sees the same passion and excitement for music in the eyes of her students. She is so proud that none of  them have tried to break any bones (yet) to avoid performing.

hOWLers are characterized by their proclivity for making musical noise with their mouths. They can be found humming, whistling, beatboxing, and singing at almost any given moment and particularly when they are together in their natural habitat; freestyle rap and mellow acoustic guitar-vocalist duos are frequent. When they're not making noise, the hOWLers are often observed eating in creative ways, doodling on manila folders, and writing acrostics.
