Some of Femi Kuti's songs and videos on youtube are quite a show of jamming musicianship. It is apparent that he and his band mates have been tuned into the rolling and grooving of live music propulsion for a long time. The horns really drive the train of a live jam right along, weaving through their world music in a wonderful, sweet juicy way.
I'd love to go to the Minnesota Zoo show. The venue is so very nice. My wife has put the kibosh on most live music though, due to my unemployed status.
