Mark Johnson is a Grammy award-winning producer and engineer, and co-founder of Playing for Change.
After a decade working with some of the most renowned names in the music, film and television industries, Mark came up with the idea for Playing for Change – an innovative and mobile technique used to record musicians all over the world and combine their voices together.
Mark Johnson and his crew literally “connect the world” by capturing stunning musical collaborations that blend diverse styles of music into powerful performances.
Their “Stand by Me” music video mixed the performances of 18 street musicians, a South African Choir and a Native American drum group into a clip that had over 30 million views on YouTube.
"Stand by Me" laid the foundation for the best selling CD/DVD set Playing For Change: Songs Around The World, which debuted at #10 on Billboard's Pop Chart in April 2009.
Since then the Playing for Change Foundation has opened music schools around the world, and has provided valuable resources for musicians.
They’ve also announced a new project coming out in May 2011.

You may not recognise his name, but Michael Young is one of the most important figures in South Africa’s political history.
In 1985, the London-based businessman arranged secret talks between the ANC and the establishment Afrikaaners, giving the opposing parties an opportunity to get to know each other and negotiate.
These talks later became instrumental in bringing down the apartheid regime, getting Nelson Mandela freed from prison, and making way for South Africa’s first democratic elections in 1994.
In 2001 Young was awarded an OBE by the British Empire for his contribution to international human rights. He was also the subject of Channel 4’s made for TV drama, Endgame.
Young rarely speaks about his role in history, but many believe South Africa may not have seen the breakthrough it saw without him.
