In his teen years, Johannes formed the band Chain Reaction (later Anthym) with Hillel Slovak, Todd Strassman, and Jack Irons.^[3] This band was later renamed What Is This. Todd Strassman was replaced by Flea, who was replaced, upon leaving the band, by Chris Hutchinson.

In 1987, Johannes and Natasha Shneider released the album Walk the Moon under the MCA label. Reportedly, Chris Hutchinson and Jack Irons played on some of its tracks.

Eleven was formed in 1990 and released their debut album Awake in a Dream in 1991, which included the pop based singles "Rainbows End" and "All Together". They followed this with regular releases Eleven in 1993, Thunk! in 1995, Avantgardedog in 2000, and Howling Book in 2003.

Johannes was the only other contributor on the 1996 debut album by Jason Falkner, Jason Falkner Presents Author Unknown.

He would participate in the tour for the album and appears on the live DVD, Over the Years and Through the Woods in the main concert.
