Jazz leader of New Orleans' Camelia Brass Band, D'Jalma Ganier, taught Louis Armstrong to play trumpet; Armstrong would then popularize the New Orleans style of trumpet playing, and then expand it. Like Jelly Roll Morton, Armstrong is also credited with the abandonment of ragtime's stiffness in favor of swung notes. Armstrong, perhaps more than any other musician, codified the rhythmic technique of swing in jazz and broadened the jazz solo vocabulary. The Original Dixieland Jass Band made the music's first recordings early in 1917, and their "Livery Stable Blues" became the earliest released jazz record. That year, numerous other bands made
Dixieland back onto the jazz circuit after years of not playing (e.g., Kid Ory and Red Nichols). Many Dixieland groups of the revival era consciously imitated the recordings and bands of decades earlier. Other musicians continued to create innovative performances and new tunes. For example, in the 1950s a style called "Progressive Dixieland" sought to blend polyphonic improvisation with bebop-style rhythm. Spike Jones & His New Band and Steve Lacy played with such bands. This style is sometimes called "Dixie-bop". Lacy went on to apply that approach to the music of Thelonious Monk, Charles Mingus, Duke Ellington, and Herbie Nichols. While
