Well, there's a misnomer if ever I heard one, mostly cuz there's nothing at all "progressive" about it. That word brings to mind a composer actually stepping out of the box & surprizing his listener, as in "progressive rock." This has a single, repetitive groove that never alters. Where's the challenge in that?
I again apologise for my lack of understanding of this type of stuff. It just seems that anyone with a minimal understanding of cut & paste can do it, & that doesn't make it art. Rap seems like a more legitimate art form to me, because there's a challenge in fitting in words to rhythms & still have meaning & substance.
I have tried my own hand at this sort of thing (I think I actually failed at it, cuz mine kept changing), & it amazes me that there are ppl that like it. After a minute of the droning, I lose interest. Perhaps it's my ADHD.
FMF, a band I was in for a cpl yrs, did some droney stuff, live, one time. I was "zoning" in a jam & just kept the same pattern going, & we lost the audience after awhile...perhaps I didn't do it right, but I straightened up (after a yell from the drummer) & we finished with our usual aplomb. That was a lesson well learned for me, though. Our audiences expected & deserved more, & they always danced to our music.
The "live" Dj's who pop this stuff in & let ppl dance to it are not there for listeners, I guess. It's evidently there for a whole nuther reason than music appreciation or interaction with an audience.
