A flavorful stew on Guitar Night

One of the great pleasures of John Pisano’s weekly Guitar Night programs at Spazio in Sherman Oaks is their utter unpredictability. Some evenings, the emphasis is on the delicate, laid-back interweaving of two acoustic guitars. Other evenings feature brisk, straight-ahead, electric guitar swing. Still others showcase the blues, in all its infinite, colorful variety.

But, even given that wide range of possibilities, Tuesday night’s program was a one-of-a-kind event. The guest guitarist was the multifaceted Anthony Wilson. The juxtaposition of his youthful vitality against Pisano’s mature sense of swing promised intriguing results. An additional ingredient -- the Hammond B-3 organ playing of Joe Bagg (supplemented by the drumming of Kendall Kay) -- enhanced the menu for an even tastier musical feast.

The mood was casual and relaxed, and a full-house audience was more than willing to lower the level of conversation and concentrate on the spontaneity on the stage. Selections were mostly standards -- “Almost Like Being in Love,” “My Heart Belongs to Daddy,” “I’m Old Fashioned,” “All the Things You Are” -- delivered with articulate musicality.

Pisano is a masterful accompanist, famous for his capacity to adapt to every imaginable style. But Wilson and Bagg asked for more than accompaniment, demanding that Pisano join them in adventurous journeys through the expanded harmonic and rhythmic byways of the well-known tunes.

Often, and especially in “All the Things You Are,” the daring quality of the improvised counterpoint triggered smiles of acknowledgment between the players.

And in the final number, an untitled but relentlessly propulsive country blues, Bagg’s funk-driven organ groove combined with exuberant back-and-forth riffing between Wilson and Pisano to produce the most buoyant moments in yet another immensely entertaining Guitar Night.
