As a visual artist, Broken Arrow, Okla., native JD McPherson is well versed in the process of working within clearly defined formal parameters, and he employs a similarly rigorous discipline with his music. On Signs & Signifiers (Rounder, April 17), McPherson’s seductively kickass debut album, produced by JD’s musical partner, Jimmy Sutton, this renaissance man/hepcat seamlessly meshes the old and the new, the primal and the sophisticated, on a work that will satisfy traditional American rock ’n’ roll and R&B purists while also exhibiting McPherson’s rarefied gift for mixing and matching disparate stylistic shapes and textures.
