We got the lineup to the 32 annual Harmony Festival right here. Lauryn Hill, Slightly Stoopid, Steel Pulse, Galactic, and Fishbone lead the charge. The festivities go down in Santa Rosa, California from June 11 to June 13. See the full linup in the MFW Harmony Festival Guide.
On an unrelated note, I once spent an evening driving Fishbone around town looking for a strip club.
