The documentary Turn It Up! A Celebration of the Electric Guitar -- which collects a crowd of well-known musicians to take viewers on "an emotional exploration of the electric guitar and the people who fall under its spell" -- will be released on home video tomorrow. But we have the premiere of a bonus clip featuring Heart's Nancy Wilson, in which she looks back on her early days playing alongside her sister Ann.

Seeking to explore the "rich bond between musician and instrument, and the pilgrimage to find the ultimate guitar and perfect tone," Turn It Up! puts host Kevin Bacon on a trail of interviews with a long list of guitarists that includes Slash, Les Paul, B.B. King, Steve Howe, Paul Stanley, Robby Krieger and Steve Lukather — as well as Wilson, whom you can watch in the clip above. The movie's release follows an Indiegogo campaign that — although it failed to raise the $75,000 sought by director Robert Radler — raised the project's profile considerably.

"I gave up the guitar to become a filmmaker. About five years ago, my son started playing, so I pulled my 1968 Gibson out from under the bed, and it all came flooding back," director Robert Radler told Guitar World. "Then my dad was in town for the holidays, also five years back, and I played for him and told him all about my little guitar collection. He said, 'You need to make a film about the electric guitar!' I realized at that time that my whole career consisted of works for hire — nothing for myself. This one was personal and I had to do it. I wanted to share the joy of rediscovering the electric guitar."
