Angel'in Heavy Syrup was an all-female Japanese psychedelic rock band formed in 1990 in Osaka. Emerging from the Japanese noise rock scene, they were influenced by krautrock bands such as Amon Düül II, but drew primarily from psychedelic and progressive rock, resulting in their characteristic ethereal neo-psychedelic sound. After the release of their last album in 2002, the band appears to have fallen into indefinite hiatus status.
