Black Dog is more than a tribute. Greg Kaye, John Ziganto, Kevin Ward and Joe Cuttone are faithfully reproducing memories of a rock era where music was grand. For those who weren’t around to experience it, it is a trip down memory lane. For those that never experienced it, it will open a new chapter in great music. Led Zeppelin crosses generational bridges with the pure essence of  organic, raw rock energy. It is a privilege to be part of this project.  Who's Next started the movement and Black Dog  was the passion and desire to keep that movement going forward. In that, Who's Next now is converted into a question. In the Rock (definitely Rock) 4 (four diverse musicians) Sure (You can bet it will be entertaining) Who's Next?
