Beaver’s jazz bands wrapped up their 2009-10 season with the Spring Jazz Café in the Black Box Theater on the evening of May 13. Thirty-two upper and middle school musicians in seven different bands performed classic jazz, blues, pop and Latin pieces. The concert, billed as a “special farewell to seniors,” was the last for six seniors, some of whom have been mainstays in the jazz program since middle school. Veteran faculty member John Clippinger played tenor sax with the senior band, which included “In a Sentimental Mood” (Duke Ellington) in its set list to match the evening’s emotion.
