Sticking with Mad River Brewery here for a minute, local country lovers Cadillac Ranch are making the blocks-long trip to the Tap Room to get you up and swaying the night away. As you guessed, it's a free show starting around 6 p.m. Kids are welcome and so are dogs as long they're on leash, but feel free to leave both at home if possible. The Westhaven Center for the Arts is hosting an Open Blues Jam with Seabury Gould & Friends at 7 p.m. tonight. Players of acoustic or electric blues are asked to bring their instrument along to participate in the community jam. Should that be your jam, you'll be able to get in for free. If you'd rather be a spectator — nothing wrong with that — you'll be asked for a $5-10 cover charge to get in. Up from the lovely armpit of California, Fresno's roots-rock duo Cloudship is stopping by Six Rivers Brewery at 9 p.m. for a free show influenced by alternative rock, grunge rock and progressive rock. Welcome the band to our strange land with trees and water.
