The vocalist, multi-instrumentalist and YouTube star Jacob Collier has some very famous fans.

Music industry titan Quincy Jones described him as an absolute genius and asked to work with him.

But Jacob declined his invitation and suggested instead if they could just be friends.

He wanted to make his first album on his own terms. The gamble paid off as he went on to win two Grammy awards.

And now, at just 23 years old, he is performing his own Prom at the Royal Albert Hall.
