Led Zeppelin

Producer Kevin Shirley shares the story with UCR.

He helped filmmakers correct a key detail in the new documentary.

Rock's biggest acts entered the new decade with new lineups, new sounds and new facial hair.

He tells UCR how his father, John Bonham, helped create one of the band's most famous songs.

John Bonham's son will pay tribute to his "favorite Led Zeppelin album of all time."

"We were all very tired and under pressure and it just came to a head," he later explained.

Documentary mixes dazzling rare footage and new interviews to chronicle the band's early years.

Filmmaker Bernard MacMahon recalls how the guitarist decided to be part of the documentary.

The singer performed powerful versions of "Me and Bobby McGee" and "Babe I'm Gonna Leave You."

'Becoming Led Zeppelin' will hit theaters next month.
