Since the band can be formed, it can also be broke up at any certain point. Many groups disbanded when their popularity reached its peak because one or more members want to establish their own solo career. Some artists quited the bands because they wanted to pursue different musical style. Most of the time, the disband naturally occured when the group's popularity declined and artists did not want to continue with the band. But for whatever reason, the artists who chose to continue their musicianship usually faced the hardship of making a name for themselves. The majority of them could not dubplicate the success as when they were in the band - some later retired. These are the list of those who used to be in the popular bands, but afterward could only make one lone hit for themselves.
