Julius Fucík was a Czech composer and conductor of military bands. He became a prolific composer, with over 400 marches, polkas, and waltzes to his name. As most of his work was for military bands, he is sometimes known as the "Bohemian Sousa". Today his marches are still played as patriotic music in the Czech Republic. His worldwide reputation rests primarily on two works: "The Florentiner March" popular throughout much of Europe and the "Entrance of the Gladiators", which is widely recognized, often under the title "Thunder and Blazes", as one of the most popular theme tunes for circus clowns. This arrangement for clarinet quartet includes the following parts: Bb Clarinet 1 or Eb Clarinet, Bb Clarinet 2, Bb clarinet 3 or Eb Alto Clarinet, Bb Bass Clarinet.

"Entrance of the Gladiators" op. 68 or "Entry of the Gladiators" is a military march composed in 1897 by the Czech composer Julius Fucík. He originally titled it "Grande Marche Chromatique", reflecting the use of chromatic scales throughout the piece, but changed the title based on his personal interest in the Roman Empire. In 1901, American publisher Carl Fischer published a version of this march, arranged for American wind bands by Canadian composer Louis-Philippe Laurendeau, under the title "Thunder and Blazes". It was during this period that the song gained lasting popularity as a screamer march for circuses, often used to introduce clowns. Today it is known mainly by this association, even though the title and composer are relatively obscure. The march receives the occasional concert hall performance, such as at the 2007 Last Night of the Proms.
