Benny Goodman (clarinet)
Louis Armstrong (trumpet/vocals)
Chick Webb (drummer)
Count Basie (piano)
Duke Ellington (piano)
Cab Calloway (band leader)
Glenn Miller (bandleader)

Add to Amyhaha list:
Harry James
Lionel Hampton
Tommy and Jimmy Dorsey
Ella Fitzgerald, Anita o'Day, Billie Holiday, Mel Torme, and Joe Williams

Arguably, Duke Ellington is perhaps the most influential (combination) composer/arranger/performer of all time.

This is VERY much a matter of person taste and opinion. there is no absolute answer.

Modern day: Harry Connick, Jr.

Glenn Miller.
