I definitely dig the echo on the intro riff, It's really active but it's not jarring at the start of the song since it's kind of muffled. The first percussion instrument, that comes in at around 0:57, is a little loud, especially compared to the kick that comes in around there. It takes a lot of attention away from the other instruments in the song. Other than that, there's a ton of variety and it all flows really smoothly together, and you make really good use of the wah-like effect. The beat also changes up frequently enough to keep things pretty interesting along with the new riffs.
4.5/5 stars, but only because of the level of that first percussion instrument. I'd give it a 4.75 if i could because it's not that big of a deal but it definitely detracted from the intro in my opinion.
