Keith Richards’ blending of rhythm and lead guitars, the “ancient art of weaving,” is nothing new. In fact, it’s relatively common. It doesn’t take a trained ear to recognize, but one night with the southern guitars of The North Mississippi Allstars and Anders Osborne is enough of a case study in showing how to do it properly. Their combined recording effort under the moniker N.M.O. (North Mississippi Osborne), “Freedom and Dreams,” sparked an extensive trek across the states and included a night at The Ogden Theatre in Denver, Colorado.
