No Pobre TV. This DVD features up-close-and-personal views of four of the finest musicians of the modern age. The InstruMENTAL Inspirations DVD features four virtuoso musicians play and discuss their influences and their past. Mike Portnoy. Billy Sheehan. Tony Macalpine. Derek Sherinian. If you are a musician, you should certainly know these four outstanding artists. I would venture that every drummer in the world knows the work of Mike Portnoy. The play on words "instruMENTAL inspirations" tells the story. Whether you are a musician or not you will be entertained and inspired as you listen to their performances and hear their stories
