I absolutely love the metaphor of the meandering river as it relates to improvising within a musical structure. This post should be required reading for anyone playing in a band context (really any group musical context that is not going entirely from sheet music). I particularly like the example video from John Hiatt, his muted strumming (starting at 2:43) is such an easily understood and observable example of playing around within and outside of a rhythmic structure. I love your original track at the end, needs some kind of droning noises accompanying I think and maybe a dirge vocal :)
Much love - Carl
Thank you. I was afraid that maybe my point will no be as clearly understood as I intended it to be but seeing your comment I fear no more :) I'm not yet sure what this track needs. I agree it need some kind of droning noises and I think they need to be organic - maybe some chimes or something similar sounding.
