The Dorchester Center for the Arts (DCA) presents in May the annual Young People’s Art Show, featuring artwork in a variety of media from school-aged children in Dorchester County. The exhibit will run through May 28, and sponsoring this month’s show is Delco Packaging Products. An Artists’ Reception and Awards Ceremony will be held this Saturday, May 14, 5 – 7:30 p.m. The reception will include live entertainment by students of Anne Watts and kid-friendly free refreshments. DCA extends its appreciation to Renee Hesson, coordinator of Instruction, and the art teachers from Dorchester County Schools for their assistance with this exhibit. • Landscape Painting Workshop June 4 DCA will present “Landscape Painting,” an intermediate to advanced student workshop by nationally-recognized artist David Grafton on June 4 from 10 a.m. to 6 p.m. Mr. Grafton is known for his atmospheric landscape paintings and bold abstracts, and his work is featured in collections throughout the U.S., Canada, Japan, and Europe. He maintains a gallery in Easton. Students may work in watercolor, oil, acrylic, or pastel and will learn how to make paintings come alive with atmospheric narrative. Also shown will be how to use a snapshot as a thumbnail sketch, and how to work small, outdoor studies into large studio paintings. Students should bring a lunch and beverage and there will be a one-hour lunch break. Fees are: $95 DCA members; $125 non-members. To register, call 410-228-7782. • Baltimore Mandolin Orchestra returns to DCA on June 5 The Baltimore Mandolin Orchestra (BMO) will present a concert in the George B. Todd Performance Hall on June 5 at 3 p.m. This is the second time BMO has come to Cambridge, as it was the first concert performance on the second floor when the facility opened in 2014. Mandolin orchestras were enormously popular all across America at the beginning of the 20th century. This was a time before television, before computer games, and before iPods—a time when people made their own music and would play it at the drop of a hat for the enjoyment of their friends and neighbors. The Baltimore Mandolin Orchestra was founded in 1924 — toward the end of the mandolin’s heyday in this country — by Baltimore band leader and music teacher Conrad Gebelein.  After lapsing into two periods of inactivity precipitated by the Great Depression and World War II, the orchestra was restarted again in 1975 by Gebelein and it has been going strong ever since. The orchestra’s current director is Kristin Turner, who took over the baton in 2011. Tickets for the Sunday afternoon concert are $12 for DCA members and $15 for nonmembers. Children 12 and under are free when accompanied by an adult paid admission. To purchase tickets by phone, call 410-228-7782.
