'Groove In G' by multiple Artists - Song Around The World | Playing For Change (Music - Instrumental, Video)
Quoting from the introduction to this video (which was published on April 21, 2011):
Get this song on our album "PFC 2: Songs Around The World": http://bit.ly/PFC2SATW
We started this track in West Africa with a musical group named Tinariwen. We asked them to play a groove in the key of G, then as we traveled the world we added more musicians to the song.
Over the course of our travels, it transformed into a global jam with its roots in the blues.
