Composer Stephen Bulla's most recent work, North Bridge Portrait, will be featured at the Concord Band's Winter Concert. The work, commissioned by the Band on the occasion of its 40th anniversary, is based upon authentic musical themes of the Amer ican Revolutionary period. Stephen Bulla received his degree in arranging and composition from Boston's Berklee College of Music, graduating magna cum laude. While at Berklee, Steve developed an interest in the commercial music field, eventually leading to his present schedule of full time composing and recording production. In 1980 Mr. Bulla joined "The President's Own" U. S. Marine Band and White House Orchestra as Staff Arranger. In that position he was responsible for the production of music that encompassed many styles and instrumental combinations, most of which were performed for Presidential functions and visiting dignataries. His musical arrangements for such per formers as Sarah Vaughan, the Manhattan Transfer, Mel Torme, and Doc Severinson have been featured on the PBS television series, "In Concert At The White House." Mr. Bulla's commissioned concert works include instrumental compositions that are performed and recorded internationally. The Dutch, British, and New Zealand Brass Band Championship organizations have all commissioned competition pieces from his pen.
