Creating "Flow" in Music

This is a video of my rock band that I toured with for 8 years. All the songs from our first CD stemmed from our performances...someone would start playing and the rest of us would follow. We did this night after night until a full song was developed. We never had one rehearsal so this band is a true reflection of "flow" can be established. BTW...don't make fun of the way I look in the cartoon that was made of the band.
