Side project

In popular music, a side project is a project undertaken by one or more people already known for their involvement in another band. It can also be an artist or a band temporarily switching to a different style. Usually these projects emphasize a different aspect of that person's or that band's musical interests that they feel they cannot explore within the boundaries established by their main project. Side projects can later become full-time endeavours, but should not be confused with quitting a band for a solo career or another band.
