Rob Witmer, one of our esteemed curators for the 12 Minutes Max showcase on March 18 & 19, begins a series of previews of the artists he and Matthew Richter chose for the performance: Does anyone remember the Baithouse restaurant on Seaview? Charles Leggett does. So much that he's written a poem about a live jazz performance he saw there while eating the best crab sandwich in the Seattle. Mr. Leggett writes about jazz with the artistry of someone who himself is a fine musician, an understanding he has reached by playing blues harp with bands all over Seattle for the last ten years. In his piece for 12 Minutes Max, Charles uses his verbal eloquence to evoke some of the great jazz recordings by Percy Mayfield, Red Garland, and Big Bill Broonzy.
