The noun razzmatazz is a colorful way to talk about activity that's meant to impress or distract people with its showiness. Your brother's magic trick might be truly remarkable, or it may be nothing but a bunch of razzmatazz.
The razzmatazz of a politician's television ads can hide the fact that she doesn't really have anything new to say about the issues, and the razzmatazz of a marching band's fancy uniforms might distract from the fact that the instruments are all out of tune. The noun razzmatazz probably came from razzle-dazzle, or "showiness," and it's probably also connected to jazz, both the word and the music itself.
