Normally, I avoid YouTube comments like the plague, but gotta give it up for the top comment there:

oh ok, when captain beefheart does advanced polyrhythms and experimental time signatures he's a "visionary" and "avant-garde musician" but when i do it i'm "annoying" and "need to leave guitar center"

It's a great album, but I probably wouldn't start there. Safe As Milk (https://en.wikipedia.org/wiki/Safe_as_Milk) is a more straightforward blue album, or the more "experimental-yet-commercial" Clear Spot (https://en.wikipedia.org/wiki/Clear_Spot).

Edit: I wanted to add that the first few times I listened to Trout Mask Replica I really didn't like it and didn't get why anyone would think it was good.
