One-man band Big Jon Short, who normally holds down the First Friday Blues at The Porch, is performing this month on the second Wednesday. Armed with foot percussion, a National Reso-phonic Guitar and Lowebow cigar-box reso-hillharp, Short’s high-energy performances tap into the heart of the songs, regional styles, and folklore of the blues and its importance to American music. Free admission for the music; table reservations recommended if you plan to have dinner.
