Two upcoming groups of concerts have a focus on social and/or ecological change.

The Roots and a wide variety of acts will be appearing at the Monterey Music Summit, October 20th and 21st:

Performers are invited to participate not for their talent and popularity alone, but also for their willingness to speak openly on current political matters, and for their commitment to positive social change.

Global Fusion 6 is a series of concerts in Hollywood presented by Immigrant Magazine, ExitSigns.com and Global Artists Network:
a fusion of performers from around the world celebrating the diversity of cultural artistic expressions while promoting the mutual ecological duties of consuming less and preserving more.

The October 18th Global Fusion 6.1 show will include Cypress Hill, The Shapeshifters, Tigarah and 2Mex.
