Query: George Masso

George Masso has played at the annual Sweet & Hot JazzFestival in Los Angeles over the Labor Day Weekend many times. The sturdy tromboning of George Masso has been an inspiration to many young instrumentalists who have come under his tutelage. If you love jazz, listen to this quiet, unassuming artist play some of the most beautifule trombone your'll ever hear.
