When it comes to influence is there anyone more vital to modern American music than Woody Guthrie? No Woody Guthrie, no Bruce Springsteen. No Woody Guthrie, no Bob Dylan – and a world without Bob Dylan would be ever bit as sparse and bleak as a world without John Lennon. It may be 'cooler' to concentrate on the debt that rock n' roll owes the early blues pioneers, but the power of folk music is equally as vital in shaping the musical landscape of the 20th Century and no one did more to bring it to the world than the genius of Woody Guthrie. So wave you folk flag with this Woody Guthrie T-shirt.
