Bobby McFerrin raised the spirits of his Moscow audience at the Tchaikovsky Concert Hall making fans between the ages of six to sixty really happy.

It’s not just McFerrin’s four-octave range and incredible vocal techniques that make him a wonder of the music world, it’s also his powers of improvisation and the joyful energy he constantly radiates.

“It's like having a kid and giving him some manuscripts and some scissors and you tell him just to cut it up and then put it all back together again. So you give him some Bach to cut up and some Ellington and then you put it all together,” McFerrin says.

His performances never have any programmes. Each of them is a unique event. McFerrin challenges the audience just to flow with the music, no matter if it's a Mozart classic or jazz fusion by Chick Corea.

McFerrin could sing anything, but it’s probably the song “Don’t worry, be happy” for which he’s best known.

“I'm walking on the street one day in New-York city and I see this guy's face, it turns out that he is a very known Indian guru and under his face are the words ”Don't worry, be happy“, and I just start singing it, so that I won't forget it,” remembers McFerrin.

That was 20 years ago. Now McFerrin is 58, he's won ten Grammys, released around 15 solo albums and also conducted several symphony orchestras.

He also leads his own ‘voicestra’, which consists of twelve singers.
