I write and send out a monthly newsletter, Switchblade, over on Substack. It’s all about music that cuts through the status quo—think how early rock ‘n’ roll intersects with Jim Crow laws and integration, why power chords forever altered our emotional response to music, and the evolution of screamed vocals. It is inspired by, and will include updates on, my forthcoming biography of iconic switchblade-wielding Native American musician Link Wray!
