Yahoo on Friday continued its shift to online content with a line-up of free streaming concerts by music stars such as Usher, Michael Franti, and The Dave Matthews Band. A Live Nation Channel on Yahoo Screen promised to serve up a new live concert daily beginning on July 15 when The Dave Matthews Band performs two sets. In todays on-demand entertainment environment, live experiences are the only ones that we all share together, at the same time, Yahoo chief marketing officer Kathy Savitt said in a release. Together with Live Nation, we are excited to bring millions of fans together to share these moments through the new Yahoo Live experience.
