The Stevie Nicks documentary 'In Your Dreams' is having its single-night showing in theaters tonight (April 2). To commemmorate the occasion, Ultimate Classic Rock is giving away a poster of the film's artwork signed by Nicks, courtesy of Abamorama.

'In Your Dreams' follows the Fleetwood Mac singer throughout the creation of her 2011 album of the same name. Nicks has said that the time she spent working on the record was "the greatest year of my life," adding that the experience was "the day the circus came to town." Both the movie and the record were co-produced by Dave Stewart, formerly of the Eurythmics. You can watch an exclusive clip from the film here.

The documentary is being shown at more than 50 theaters across the country, For locations, times and tickets, visit the film's website.
