"Akasha and Ska Brewing present Simmer Down Sound, one of Chicago’s most diverse and unique reggae and dancehall scenes. Simmer Down Sound (“SDS”) is a Chicago-based movement honoring the extraordinary musical culture and legacy of Jamaica. It was founded by Cosmos Ray in 2011 and started as a monthly event at the Double Door, an iconic Chicago music club. Many reggae nights in Chicago are focused on a single style of reggae and are attended by only one group of fans. However, SDS set out to create a night that covers as much territory as possible of the steeped fifty-year history of reggae music

Our philosophy derives from Jamaican ska anthem “Simmer Down,” by the Wailers and the Skatalites. At the time of the writing of this song, Jamaican youth were embroiled in violence. In an effort to dispel the bloodshed, Bob Marley used his lyrics to plead with the youth of Kingston to simmer down. By the same token, SDS asks its participants to leave ideology, religion, politics and other divisive beliefs at the door, and to “simmer down” together around art and music in order to promote greater awareness, acceptance, and peace.

We want to give big love to everyone who supports this movement!
