It’s not officially summer until the outdoor music festivals start. And though the Aqus Foundry Festival is no Coachella, the daylong music fest gives the North Bay a small fix of music and sun while raising money for homeless services. The lineup includes the Rowan Brothers, pop-folksinger Lauren O’Connell, the sassy women of Foxes in the Hen House, the Incubators, Side O’ Smokehouse and the Mighty Groove. Proceeds benefit COTS, who provide 350 beds every night to the homeless and serve over 124,000 meals per year. Break out the shorts and dance in the grass on Saturday, June 8, at Foundry Wharf Business Park. 625 Second St., Petaluma. 11:30am—7pm. $10—$20. 707.762.5999.
