The baroque music of the seven musicians called PLUM celebrates the season today at 3 p.m., in the Florence Hollis Hand Chapel at Mount Vernon College on Foxhall Road. The group will play such pieces as "La Sonnerie de St. Genevieve du Mont de Paris" and "Greensleeves."

Lois Pipkin, harpsichordist and director of PLUM, describes their audiences as specialized and knowledgeable. "I spend a lot of time in the Library of Congress researching, trying to find pieces in their original form so that we may play directly from the first manuscript of the composer," she says, adding that they try to come up with unusual repertoires.

Featured with PLUM will be mezzo-soprano Linda Allison singing Bach arias and a cantata of Telemann. The musicians play on early instruments: baroque flute, baroque violin and cello, baroque harpsichord, piano forte and organ. Three of the members also perform with the Washington Bach Consort and three are faculty members of the Selma Levine School of Music.

"We have been together since 1981," says Pipkin. "The name PLUM is the acronym of the names of four of the players. We are all professional musicians. Yet we wear many hats. PLUM gives us a permanent opportunity to perform the music we love best."
