Bio-Violence is the fourth album of Drowned, released by Cogumelo Records. Bio-Violence focuses their lyrics on conflicts and current wars, the environmental degradation, Brazil and its problems, passing by influence and imperialism of the great nations. Although arid it is the reality glimpsed by the band, the intention of Drowned is to alert and take over the people to reflect about it. There is still time so that a less shady future is built. This new work stands out in relation to the previous ones in the dynamics and complexity of the arrangements, maintaining, however, the characteristic aggressiveness and style of Drowned. The album, 10 tracks, 39 minutes long, had production under the responsibility of guitarist Marcos Amorim and the own band. The graphic artwork was elaborated by vocalist Fernando Lima.
