New documentary "Becoming Led Zeppelin" traces the journey of the legendary band's four members from their humble musical roots to their groundbreaking success in America. (Feb. 21)

With new interviews, rare archival footage and a skull-rattling soundtrack, there's a whole lot to love about this theatrical experience.

Becoming Led Zeppelin' is an explosive and exciting (if rose-colored) documentary of the band's origin story and meteoric rise to fame.

Full of never-before-seen footage of the band’s first 18 months, interviews with John Paul Jones, Jimmy Page, Robert Plant, and new audio from the late John Bonham, the first authorised documentary about the best hard rock band to ever do it assumes a lot about what its audience already knows.

A thoroughly researched documentary blessed by control freaks who still can’t, or won’t, wrestle with the less flattering parts of the band’s history.

DECIDER spoke to director-writer Bernard MacMahon and producer-writer Allison McGourty about this project that was decades in the making.
