Up and running as a single-serve site since long before Tumblr was a gleam in some coder's eye, it features one online music video posted every day, drawing from genres including jazz, blues, soul funk, classic rock, prog rock, experimental and more.
Recent posts have shown live performances - some rarely seen until quite recently - from Kurt Elling, the Horace Silver Quintet, Jerry Lee Lewis, Warren Zevon, Sun Ra Arkestra, Ray Charles, Dave Douglas Quartet, Max Roach Quintet with Abbey Lincoln, Tower of Power, Preservation Hall Jazz Band, Sly and the Family Stone, Albert King, Oliver Nelson and the Berlin Dream Band, Jefferson Airplane, Most Allison, Randy Newman, Betty Carter, the Morells, David van Tiegham, and Duke Ellington.
Sure, you could just go to YouTube, start typing names into the search engine, and see what happens. But why not take advantage of the work someone else (i.e. yr. humble StLJN editor) has already done to find the good stuff? You'll find all these clips, plus thousands more from the carefully curated archives, just by going to http://heliocentricworlds.blogspot.com/.
