How To Grow A Band is a 2011 music documentary film about the early days of American progressive bluegrass band Punch Brothers. The film stars Chris Thile, Gabe Witcher, Noam Pikelny, Chris Eldridge, Paul Kowert and Greg Garrison and features interviews with a number of notable musicians including Yo-Yo Ma, John Paul Jones of Led Zeppelin, Jerry Douglas, bassist Edgar Meyer and Sara Watkins of Nickel Creek. The film's narrative structure tracks mandolinist Chris Thile's ambitious four movement suite, "The Blind Leaving the Blind" as it follows the band on their first tour as Punch Brothers in the United Kingdom and United States in early 2008 leading up to a triumphant performance at Jazz at Lincoln Center's Allen Room in New York City.

How to Grow A Band was directed by Mark Meatto and produced by Michael Bohlmann and Mark Meatto and edited by Purcell Carson and Mark Meatto. Daniel Algrant and Bert Keely were executive producers. The film premiered at the 2011 Nashville Film Festival.
