Excerpt from the performance of Gary Burton at the Montreux Jazz Festival 1971, with special guest Larry Coryell. I think they play "Freedom Jazz Dance", but I'm not sure.
I made this video out of two sources: one fairly good color but incomplete version and one bad black 'n white more complete version. The source switches around 1:15. The audio I took from the b&w version, and removed the noise a bit.
Gary Burton - vibes
Larry Coryell - el. guitar
Clint Hinton - bass
David Lee - drums
