Having spent the last few years working on compositions with a range of South African and African artists, Kellerman has recently released a new album titled 'Half Moon', which was mixed in Los Angeles by Grammy-winning engineer Husky Hoskulds.
Kellerman says that he thrives on experimenting with the shades, textures and colours that his magic flute is "capable of painting", and creatively blending this with other instrumentation and vocal sounds.
Last year Kellerman won the South African Music Award, (which is the South African equivalent of a Grammy) for best instrumental album. He performed in 2010 at the FIFA Soccer World Cup Closing Ceremony to a global television audience of 700-million people.
His flute-playing is featured on the soundtrack of the film 'Eye of the Leopard, which won an Emmy Award.
Kellerman is passionate about teaching and empowering young people, and has sponsored the living expenses of 10 kids at a children's village in South Africa for 14 years, and financed the building of a house in another children's village. He also facilitates the teaching of young dance and music students.
