HUDSON – The junior high a cappella group Wicked Sharp at Presen­tation of Mary Academy attended the "Voices of the (603)" workshop at the University of New Hamp­shire on Friday, Oct. 9.

The event, now in its sixth year, included an all-day workshop for a cap­pella singers, followed by a concert and competition that night at the Capitol Center for the Arts in Concord.

The girls learned about many aspects of a cap­pella, including lyrics, stage presence, vocals and beatboxing. They were inspired by performances from more than a dozen New Hampshire high school, college and ama­teur a cappella groups.

In addition, the group has been working on a video for the Macy’s All-School A Cappella Challenge. The contest requires participants to create a video of their a cappella performance of "I Want You Back" by the Jackson 5.

Junior high math teach­er Adam Shaw and music teacher Maria Gonzalez are helping the group with their performance and video.
