That high pitched noise, while probably possible with bag pipes is actually a piccolo trumpet hit. I think they show a piper in the video, but the majority of that whole song is sampled from the song “Harlem Shuffle” by Bob and Earl.
I think there’s a short sample of pipes that’s constantly repeated as a backing track. It’s not the high-pitched part, but the drone underneath everything. I’ll admit that my first reaction was to think “WTF is she thinking?” when Guin posted that (because I didn’t remember any bagpipes in it when it first came out), but after listening to it a couple of times, I think she’s right.
I hate to be the constant party pooper, but no, no bagpipes here. Definitely.
At least one track on Blackout in the Red Room by Love/Hate has bagpipes on if I recall correctly. Although it has been a while since I listened to it.
