The members, Micco and Tatsuya Kikuchi, met and became friends while they were both enrolled in music school.
Kikuchi was the main musical support for Micco at that time, who was acting as a solo artist.
After getting signed to Warner Music Group's indie label in 1999, they had two releases, but got increasingly more involved in production for other artists and gradually did less and less of their own activities.
However, the urge to write and perform their own music came back, and to commemorate this change in attitude, they resigned the company and renamed themselves 'marble' in 2003 and played shows with a backup band, but they split from the band in 2005, and Micco and Kikuchi continued their performances as a duo.
Their songs have been featured in such anime as Hidamari Sketch, Kamichama Karin, KimiKiss pure rouge and Tamayura ~hitotose~.
