Ossayol is a musical project that can be described as « indie rock » and explores sounds from classical, through folk to alternative rock. It is in the form of a trio formed by singer-guitarist Mickaël Pillisio that the band performs on stage with drummer Fred Bongo and cello player François Kaspryk.

In August 2018 was recorded the first self-produced album: « 1990 » pressed on CD / vinyl with the support of many contributors via crowdfunding.
