Birthdays and anniversaries make the best parties, and Marin’s got both this weekend. First, Rancho Nicasio is celebrating 17 years of live music and great food with an anniversary weekend that also doubles as a birthday party for singer and longtime Rancho booker Angela Strehli, the “Queen of Texas Blues,” who’s called the North Bay home for 25 years. The stars will be out for this birthday bash, with Champagne, hors d’oeuvres and plenty of lively entertainment. The next night, Strehli takes the stage at Throckmorton Theatre to sing with the Blues Broads and keep the good times rolling.
