The big band of
Jimmie Lunceford (1902)
was emblematic of the tight and stylish sound of the last phase of swing.
That relaxed sound was mostly due to the arrangements of Sy Oliver (1934-39), the brain behind
Shake Your Head (october 1934),
My Blue Heaven (december 1935),
Organ Grinder's Swing (august 1936), one of his most eccentric creations,
For Dancers Only (june 1937),
Honey Keep Your Mind on Me (july 1937), with a celebrated solo by guitarist Eddie Durham,
Margie (january 1938), with a celebrated solo by trombonist James "Trummy" Young,
Tain't What You Do (january 1939).
While in his orchestra, Eddie Durham introduced the electric guitar into jazz music.
After Sy Oliver left, he was replaced by trumpeter Gerald Wilson, whose
Yard Dog Mazurka (august 1941) and Hi Spook (august 1941) displayed
a proto-bebop approach to arrangement.
Lunceford died in 1947.
