Ft.Tony Martin, Michael Schenker, Alice Cooper. Anthony Martin Harford (born 19 April 1957), better known by his stage name Tony Martin, is a heavy metal vocalist best known for his work with Black Sabbath from 1987 to 1990 and again from 1993 to 1997. Martin was the band's second longest serving vocalist after Ozzy Osbourne. Martin has since been involved in many other projects (such as the Tony Martin Band, M3, The Alliance, Misha Calvin, The Cage, Giuntini Project, Phenomena's Psychofantasy album). Despite performing almost exclusively as a vocalist, Martin is a multi-instrumentalist, stating in an interview that he plays guitar, bass, drums, violin, keyboards, harmonica, bagpipes, and pan pipes. On his 2005 solo album Scream, Martin performed vocals, bass, drums, violin and additional guitar parts. Michael Willy Schenker (born 10 January 1955, Sarstedt, Lower Saxony) is a German rock guitarist, best known for his tenure in UFO, in addition to his solo band. He first rose to fame as an early member of the Scorpions, then achieved fame in the mid-1970s as the lead guitar player for UFO. Since leaving UFO in 1978, he has been leading the Michael Schenker Group in various incarnations. He has rejoined UFO three times, producing an album each time. He is the younger brother of Rudolf Schenker, who is still a guitarist with the Scorpions. His career has had many ups and downs, partly due to a long history of alcoholism and personal problems; still, Schenker continues to perform and record and to maintain a following, and is called a legendary figure in the history of metal guitar.
