Mr. Mod and his Bird
Evil rock duo who use subliminal messages in their music to control the minds of their youth audience. This is actually really impressive since they do it during a live concert, instead of on a record, as is tradition. Weirdly, they do it by singing a song written by someone else, Bo Bylan. They send their audience to attack a "peace ministers' meeting."
From Dell Comics' short-lived series, Superheroes #4 (May 1967).
