Sonic things:
Benjamin Earl Turner’s “HEADSPACE/BENT” samples Radiohead’s Glass Eyes right there before the Kendrick feeling part comes in, which to me is perfect because Kendrick’s use of piano in his work many times seems to recall piano elements from Radiohead
Radiohead’s Spinning Plates uses the same sort of “spinning” sound found within/directly samples The Pop Group’s There Are No Spectators - which to me makes sense, considering the theme and lyrics of both songs. Similar “whirring” sound shows up in Instant Club Hit & Planet X by The Dead Milkmen
Thom Yorke uses the same kind of synthy birdsong sound/samples Can’s Vitamin C in Dawn Chorus
The melody on Yorke’s Interference is real similar to Board of Canada’s Hi Scores
Packt Like Sardines In a Crushd Tin Box has a leading drum loop that sounds a little like Tha from Aphex Twin
I'm pretty sure there's a sample of Laurie Anderson's Langue d'Amour somewhere in Radiohead's discography, but can't remember where. Might probably also be just them using the same electronic effect
