Mary Ann Haskell

SanDiego BluesGirl Merchandise Coordinator

Mary Ann is one of San Diego's biggest Blues supporters, and has been working with Rosalea as head merchandise coordinator sine 2016.

Growing up in a musical household, Mary Ann Haskell developed a deep love of Blues music after teenage years as a Rock ‘n’ Roll girl, with a dose of Country mixed in. Realizing those genres were rooted in Blues lent a depth of authenticity and led to a musical epiphany. The Blues became her steady focus in the early 80s, and promoting Blues music has been her passion ever since. ‘SanDiego BluesGirl’ was coined at the Doheny Blues Festival, many years ago, by her fellow Blues lovers, a name she relishes living up to.

Nick Abadilla

Concert Photograpy

Nick Abadilla is a retired professional photographer having specialized in commercial and assignment work. Although his camera is stashed away most days, he occasionally applies  his creative eye toward personal projects and exclusive musical performances, specifically those of the Gourmet Blues Concert Series.  Well seasoned in editorial photography, he intuitively captures the kinetic vibe both onstage and amongst the audience. A weekend guitar player himself, Nick considers himself fortunate to count several local A-list musicians amongst his friends. His passion for authentic blues also steered him toward his new retirement hobby - handcrafting cigar box guitars under the name Blues Baby Guitars. He has completed/sold nearly 70 guitars with more on the horizon.

Dr. Barbara Kabes

Transportation Coordinator

As an original Beatlemanic, Barbara fell in love with the Blues through the British Invasion, although not realizing it at the time.  She developed a rich record collection of the Beatles, Stones, Animals, Yardbirds, and Spencer Davis, to name a few.  Reading in her teen magazines the influences of these bands were names she had never heard, Muddy Waters, Howlin Wolf, and others.  It was about 30 years later that she researched those influencers.  She was amazed to find she knew some of the songs!  She began searching for Blues CDs in the Library and at Kolby’s Swap Meet.  She would tell people she listened to dead people.  It was not until 2013 that Barbara became active in the local Blues family.  She began volunteering for Blues Lovers United of San Diego by representing BLUSD at RosaLea’s Wednesday Jam at the House of Blues.   Now you can find her in the audience of many local and national venues.   She likes to say, “I am why you play!”
