Particularly, uninterrupted by any fills, but slight variations / cymbal changes would work. I scoured my music library and the best I could come up with is the outro to Behemoth's The Satanist @ about 17 seconds (starts at about 4:16) I know some Derek Roddy-era Hate Eternal has some long stretches as well as Vital Remains. But None that I could find that was longer than the example above. Curious if you guys know of any others. I love the focus and tension that extended stretches of blast beats can give song.
