There're at least two bands called The Mysterons:

1. The Mysterons are a Dutch psychedelic rockband based in Amsterdam, featuring members of Jungle by Night and singer Josephine van Schaik. Their début EP was released in April 2015; their début full-length, Meandering, in early 2017.

2. The Mysterons were a Canadian band, active from 1990 until 2010 and based in Vancouver. The group was founded by Schatzie Boneslide (guitar, bass) and Mr. Fist (guitar, bass, keyboards).
