Jeffrey Terrace is comprised of four core members: Stevie Jick, Adam Kane, Gabe Orduna, and Russel Bollag-Miller. The band began with inconsistent jam sessions and the creation of a few instrumental songs between Adam and Stevie in 2005. A few years later, Gabe joined the band to add some texture as a bassist. After a about a year of jamming and song-making, a guitarist (Leif Inouye) joined and the band progressed and became more serious. About 6 months later, guitarists were changed, and Russel became a steady member of the group.
