RIP
He was indeed an odd character as one can see in Crimson videos from that time.
Short piece from wiki

"In the summer of 1972, Muir received a call from
Robert Fripp, and was invited to join what was to become a new incarnation of
King Crimson,
[4] with a lineup that came to be, according to Muir, focused on "group potential and creating monstrous power in music."
[2] During his tenure with the band, Muir occasionally played a standard drum kit, but more often he contributed an assortment of unusual sounds from a wide variety of percussion instruments, including
chimes, bells, gongs,
mbiras, a
musical saw, shakers, rattles, found objects, and miscellaneous drums. Muir initially appeared on a single King Crimson album, 1973's
Larks' Tongues In Aspic (the title of which was coined by Muir; when asked by Fripp what the music sounded like, Muir responded "why, larks' tongues in aspic ... what else?"),
[5] on which he is listed as playing "Percussion and Allsorts"
