Show some love for the artists who defined modern music with one of these soft, slim tees from the L.A. clothing label Friend or Foe. Founded in 2006, Friend or Foe features a collection of T-shirts celebrating John Coltrane, Muddy Waters, Lightnin’ Hopkins, John Lee Hooker and many other legends. As any true music fan knows, despite rock’s undeniable popularity and appeal, jazz, blues, and soul musicians were the real trailblazers. Rest assured that Friend or Foe’s shirts and other wares look just as good as the music that inspired them sounds.
