Arguably, surf was the first type of rock & roll to really focus on a feeling of power and aggression, playing songs faster and louder. As punk and metal rolled around, a lot of bands absorbed those influences into surf to really ramp up the ferocity. For the sake of categorization and rhyming, I've called these bands "rad" instro groups.

Here in New Orleans it’s carnival time. Nearly every night this week there are parades all over the city. Once you’ve been to enough of these parades, they lose a lot of their appeal, and as that happens your focus draws away from the flashy floats and the beads flying through the air and towards one of the most underappreciated facets of New Orleans culture: the high school marching bands. The New Orleans tradition of small brass ensembles have been slowly getting more of their due, but these marching bands don’t cut albums and are rarely experienced outside of carnival. 

What is "Rad instro"? Well, I made it up, mostly because "Rad" rhymes with "Trad". There are other words you could use: "aggro" or in the college radio world there's "loud". This is the instro music that's all about power, speed and adrenaline.
