August 13. Beacon folksinger Jake Holmes is best known for his harrowing 1967 “Dazed and Confused,” a song Jimmy Page heard him play when he opened for Page’s band, the Yardbirds. Later, when Page formed Led Zeppelin, he kept the title, came up with some new lyrics, altered the melody a tad, and—voila!—instant hard rock classic. Luckily, Holmes has since been able to pay his bills via jingles for Dr. Pepper (“Be a Pepper”) and the US Army (“Be All That You Can Be”). He plays the Dutch Arms Chapel’s John Street Jam this month with Zach Hurd, Remy de Laroque, Dan Strauss, Marty Koppel, Lynn Hollyfield, Brianne Chasanoff, and Sarah Bowman. 7pm. $5. Saugerties.
