JazzEast's only fall concert brings in-the-moment jazz to a whole new level this Friday with Phil Nimmons and David Braid. During a hectic travel schedule, young pianist and composer Braid emailed to say he and Nimmons have performed about 40 concerts together in the past six years, without having rehearsed or spoken about what---or how---they should play. "Phil often tells our audiences, 'The only rehearsal is discussing what we're going to wear,'" writes Braid, adding that the "one way to vaguely describe the nature of our performances is to say we play 'free jazz.'" Asked what it's like to play with such a renowned veteran such as Nimmons---whose career spans six decades as a jazz musician---Braid responds graciously. "I grew up in an environment which taught me to show respect for older people. However, if I thought too much about Phil's tremendous notoriety, I might be less inclined to assert my musical ideas when we perform together." After each improvised piece, Nimmons'n'Braid invite the audience to ask questions, informing their next piece. Don't be afraid to speak up.
