One of the best all-time rock albums by any measure, Imagine is nearing its 30th birthday-and here"s a marvelous tribute. You can get the original LP on CD or cassette with remixed, remastered sound and a 16-page booklet with lyrics and rare pix. Or go behind the scenes of a masterpiece-the documentary Gimme Some Truth-The Making of Imagine , featuring an unfinished film by John and Yoko, is available on VHS or DVD (DVD has surround sound, an eight-page booklet and discography). A treasured moment in rock history.
