Blues Traveler’s John Popper on New Book, Why Not To See the Dead with Deadheads, Phish Gags, and How H.O.R.D.E. Diversified From Jam Bands to Primus and Beck

Ahead of the release of his new book “Suck and Blow,” The Future Heart caught up with harmonica virtuoso John Popper on his book tour to discuss why Blues Traveler isn’t a jam band, his gags with Phish, why it’s a mistake to go to a Grateful Dead concert with Deadheads, and how booking artists like Beck and Primus on his H.O.R.D.E. tour foreshadowed contemporary festivals.
