Mike Oldfield's iconic Tubular Bells is being reissued to celebrate it's 50th Anniversary. This special collection features an unreleased demo made five years ago which, at the time, was intended to be the start of a new 50th anniversary version of the work. Then, Mike Oldfield retired, and the eight-minute introduction was shelved. Now seeing the light of day, Tubular Bells 4 Intro is the conclusion to this historic album's incredible life and may well be the last thing to ever be recorded by Oldfield.
