The musician recorded Winds of Samsara with Indian composer Ricky Kej, which earned them the nomination for their collaboration and was inspired by Mahatma Gandhi and Nelson Mandela.
Kellerman said he's hopeful that the win will allow him to play his music for more people.
“It will just help us to be given more opportunity to do what I love.”
The Johannesburg born musician says he's happy there's a good new story for South Africa.
“The message is of peace, love and tolerance about Nelson Mandela and Mahatma Gandhi that’s the message we were trying to communicate with this album.”
It took three years and 120 musicians to make this album.
Winds of Samsara reached No. 1 on the US New Age Album Billboard Charts and top 100 Radio Airplay Chart in the month of July 2014
