While I may have made release writeups for most of these (which is kind of blowing my mind right now), it's really cool to see a huge list to get a good picture of just how alive instro rock&roll still is today. So here's what I was able to dig up. I'm sure I've missed a few, please point them out. There's no meaningfulness to the order, and articles that aren't linked didn't get a writeup (no meaningfulness there either, sometimes I just didn't get around to it).
Which I'm (generously) defining as 6 songs or more unless the band explicitly calls it an EP
