Phil Ford is the author of “Dig: Sound and Music in Hip Culture.” He takes the reader on a tour of the cutting edge world of jazz musicians, Beat writers, and style arbiters who make up what is hip. Ford is a professor of musicology at the Indiana University Jacobs School of Music. His interests range far beyond the narrow field of creating rhythmic, harmonic sounds that are pleasing — or not — to the human ear. Music ties countless disciplines together. Now he’s working on a book describing magical thinking and how it relates to music and the greater world. He joins Michael Glab on this week’s edition of Big Talk.
