All of it really, but especially:
- The "Boléro Effect" section, with Vivian Stanshall announcing and Oldfield adding one instrument after another over a strange, undulating riff, and ending with the glorious "Plus...TUBULAR BELLS!" *KLAAAAANNNNGG*
- How about the fact that Mike was just 19 years old when he recorded this soing?
- After The Child's narration, the last track of Tubular Bells 3 is epic.
