Jellyfish was an American rock band that made significant waves during their short tenure in the early '90s. Formed in San Francisco, California, in 1989, the group was led by singer, drummer, and songwriter Andy Sturmer and keyboardist/multi-instrumentalist Roger Manning. Renowned for their blend of pop, psychedelia, and glam rock influences, Jellyfish's music showcased an intricate and melodic sophistication that stood out during a time largely dominated by grunge.

The band released their debut album, "Bellybutton," in 1990, which served as a showcase for their dynamic artistry, tight harmonies, and meticulously crafted pop sensibilities—capturing the attention of a devoted fan base. Their second album, "Spilt Milk," released in 1993, further cemented their reputation as pop-rock virtuosos with more elaborate arrangements and sumptuous production quality. Despite critical acclaim and a growing following, Jellyfish disbanded in 1994 after just two albums. Posthumously, releases like "Bellybutton Demos" have provided fans with a fascinating glimpse into the band's creative process, highlighting unreleased versions of the intricate work that defined their legacy in the power pop genre. Their short-lived journey, however, left a lasting impression, and Jellyfish is frequently remembered and celebrated as one of the more inventive bands of their era.
