Waterfront Park, Big Four Lawn
Free; 6 p.m.
WFPK’s next Waterfront Wednesday concert will feature headliner J.D. McPherson, who seems to have taken the advice of rockabilly pioneer Carl Perkins to “Put Your Cat Clothes On.” His popular single “North Side Gal,” from Signs and Signifiers, oozes with mid-’50s Sun Records country soul, and the rest of the album is cut from the same cloth. His stripped-down sound might even cause some of the elders in the crowd to get up and dance. Opening acts are singer-songwriters Audra Mae (6 p.m.) and Matt the Electrician (7:30 p.m.). Mae’s songs are being picked up by “CSI” and other big media outlets, while you can preview the genial Matt the Electrician’s concert from SXSW on YouTube. Remember, the music is free, but outside alcohol, coolers, glass and pets are not allowed. —Martin Z. Kasdan Jr.
