Izzi Guzman's "99 Percent" blends bossa-nova and rock styles into a lively and dynamic big band composition with colorful harmony and syncopated rhythms. Crafted from modern textures while retaining a catchy melody that listeners will remember, "99 Percent" is a journey reflecting on the feelings of being nearly completed with a goal or project, striving to reach 100 percent.

While the rhythmic scheme of this piece may be accessible for many high school jazz ensembles, the range of the lead parts in the brass and they key (concert A major) make it more suitable for advanced groups.
