FAMU's band is very flashy. Very loud and very visual. They get better as the year goes on (as most bands do) but the formula is the same. Its a very show-y band by tradition. What they gain in style, they lose in quality however. They sacrifice dynamics for loud sound and when they perform on the field, audio tearing is an issue. You could hear it in RayJ.
HOT has a more quality approach. They sacrifice loud brass sounds for a full range of instruments and dynamics. Though the music is often simple, it sounds like the music. Audio tearing is less prominent.
All in all its something you see with a lot of bands. A few bands can bridge the gap between quality playing and a loud, booming sound.
