Mike Oldfield Used VOCALOID

In 2005, Mr Mike Oldfield kindly used VOCALOID in his album "LIGHT & SHADE".

In the track "The Gate", he added "Ooh" and "Yah" to make a chorus harmonized perfectly.
In the track "Tears Of An Angel", he put some lyrics by making them like echoes with the same melodies as the ones played by the keyboard. For this track, he says that this was his first track created by using VOCALOID, and by mixing in his voice, it achieved a nice thick choral effect.
