Listening as I'm writing.
Oh that's a great sound. Reminds me of early 90s action movies. I really love how in the middle, you defy my expectations a few times. It's excellent. Ooh love those little percs shortly before the two minute mark and wait ... what is this... woah. Cool. Sudden jazzy bits. Is this called infiltration because you secretly moved a completely different style into this one? Well done. Also, I like that we get back to the classic action vibe at the end to close it off.
Reading the blurb after listening, it surprised me that you started off with the metallophone part. That somehow makes it even more impressive.
Amazing work!
