Dennis Johnson, nearly forgotten composer
NEW YORK — Dennis Johnson, a composer who in 1959 wrote a trailblazing minimalist work, a six-hour piano meditation of repeated notes and long pauses that went unheard for 50 years before being rediscovered, died Dec. 20 in Morgan Hill, Calif. He was 80.
His half brother, Don Wilson, said the cause was complications of dementia.
Until 10 years ago, long after Mr. Johnson had dropped composing for a career as a mathematician, his music was known only by reputation. References to it ...
