Five O'Clock Shadow - More than 25 years ago (1991 to be exact), five guys got together to do some street singing. They started with simple doo wop and jazz harmonies. At a time when doo wop was considered “contemporary” a cappella, these five guys wanted more from vocal music. They began to experiment. They found ways to make drum sounds with their mouths and imitated instruments such as trumpets, harmonicas, and guitars. Eventually, imitation simply wasn’t enough. With the help of simple stomp pedals, they incorporated wahs, tremolo, phaser, flanger, and distortion into their arrangements. What began as a simple a cappella group morphed into a vocal powerhouse unlike anything the world had heard or seen before. Audiences across the United States, Europe, and Asia have been witness to this revolutionary form of a cappella.
