Rex Stewart achieved his greatest glory in a subsidiary role, playing cornet 11 years in the Duke Ellington Orchestra. His famous "talking" style and half-valve effects were exploited brilliantly by countless Ellington pieces containing perfect passages tailored to showcase Stewart's sound. He played in a forceful, gripping manner that reflected the influences of Louis Armstrong, Bubber Miley, and Bix Beiderbecke, whose solos he once reproduced on record. Stewart played on Potomac riverboats before moving to Philadelphia. He went to New York in 1921. Stewart worked with Elmer Snowden in 1925, then joined Fletcher Henderson a year later. But he felt his talents were not at the necessary level, and departed Henderson's band, joining his brother Horace's band at Wilberforce College. Stewart returned in 1928. He remained five years and contributed many memorable solos. There was also a brief period in McKinney's Cotton Pickers in 1931, a stint heading his own band, and another short stay with Luis Russell before Stewart joined the Ellington Orchestra in 1934.
