FRIDAY

THE NEW TRUST

Established in Santa Rosa in 2003, the enigmatic musical project known as The New Trust (or simply TNT) returns to the Phoenix Theater for a special 15th anniversary concert alongside the equally hard-to-pin-down Bay Area band Polar Bears.

TNT’s current roster is Josh Staples (bass and vocals), Sara Sanger (guitar and vocals) and Julia Lancer (drums). Playing dark tinged punk pop with a sense of playful experimentation and just-go-for-it bravado, The New Trust is ready to celebrate one-and-a-half decades of rough-hewn musical genius - and set the stage for the next fifteen years.

Phoenix Theater, 21 E. Washington St. 8 p.m. $10. ThePhoenixTheater.com.

MISS MOONSHINE

This seven-piece alternative-folk band is made up of musicians who met at Sonoma State University while all were majoring in jazz and/or classical music. With eclectic instrumentation that includes accordion, trumpet, mandolin, guitar, bass and percussion, the one-of-a-kind band have been building a following, winning new fans every time they play. You can bet that will happen again this weekend at Red Brick, 101 Second St. 7 p.m. RedBrickRestaurants.com.

SATURDAY

POOR MAN’S WHISKEY

Northern California’s high energy distillers of bluegrass-old time-Southern rock/whatever-else-they-feel-like music just keep growing in popularity.

Poor Man’s Whiskey blends masterful original tunes with truly surprising covers, putting a wackily creative bluegrass spin on everything from Pink Floyd to Paul Simon.

Mystic Theater, 21 N. Petaluma Blvd. 8:30 p.m. $20. MysticTheatre.com.

ONE GRASS, TWO GRASS

The deliriously engaging string band known as One Grass, Two Grass, hot off the release of a new CD, returns to the Lagunitas Brewing Company this weekend. 3 p.m. No cover. 1280 N. McDowell Blvd. Lagunitas.com.

SUNDAY

‘NATIONAL LAMPOON’S

CHRISTMAS VACATION’

Boulevard Cinemas, 200 C St. Cinemawest.com.
