In September, Sweetwater Music Hall in Mill Valley, California, will host its first-ever off-site music festival. Dubbed Sweetwater In The Sun, the one-day event on Sunday, September 23rd, will be held at Stafford Lake Park in Novato, California, with performances by a number of high-profile artists from the jam scene and beyond.

After announcing its inaugural lineup last week, Sweetwater In The Sun has added Bob Weir, the renowned Grateful Dead guitarist and Sweetwater Music Hall partner, to top the lineup. Previously, the new festival announced that it would also host Steve Kimock & Friends; the supergroup, Skiffle Players, featuring Neal Casal, Cass McCombs, Dan Horne, Farmer Dave Scher and Aaron Sperske; Jennifer Hartswick Band, featuring the Trey Anastasio Band singer and trumpeter in addition to Bobby Vega and Nick Cassarino; Maggie Rose; and a duo set from Kimock and Jerry Joseph.

The festival is clearly meant to be a family-friendly affair, with a special Kids Grove Stage that will host the Little Folkies Family Band in addition to bubbles, face painting, magic, and arts and crafts for the children in attendance. In terms of sustenance, food and beverages from Sweetwater Music Hall will be sold at Sweetwater in the Sun, with the food prepped by Chef Gordon Drysdale.
