For over forty years, John Cowan has been both a participant in and chronicler of country and bluegrass music history. Whether as the lead singer and bassist of the genre-bending group New Grass Revival, a beloved personality on Nashville's WSM radio ("the most famed country music station in the world"), or the newest member of the Doobie Brothers, Cowan has had a front-row seat to seismic changes in American roots music and in the recording industry as a whole.

Hold to a Dream combines a rollicking account of Cowan's life and career with interviews with some of the biggest names in country and bluegrass, including Kris Kristofferson, Bela Fleck, Loretta Lynn, Jim Messina, John Carter Cash, Sam Moore, and Bernie Leadon. It's a fascinating look into a half-century of tradition, experimentation, and innovation in one of the most vital and enduring of American musical genres.
