Ripping CDs from Monday's #SunnO))) show, an album titled:

#观世音KANNON
观: not part of standard Japanese, Chinese in origin meaning: "watch tower" possible pronunciation:「guān」(mandarin)
世音: possibly a Japanese compound「seion」according to jisho.org "world sound/music" would be kind of a translation attempt?

Liner notes: "KANNON/CANON"

"Kannon is sometimes Kan'on, Kanzeon or Kwannon, Japanese pronunciations of Kuan-yin, Quan-uin, or Guanyin, short for Kuan-shih-yin or Guanshiyin," continued.
