He has a relatively high-pitched tenor-esque singing voice and sometimes uses a shriek reminiscent of Judas Priest's Rob Halford, although it is his baritone lows which give him a near four-octave range in the modal register. He has also sung in Gamma Ray and Tyran' Pace. Scheepers has also done guest vocals for the bands Scanner, Therion, Ayreon, and Shadow Gallery, and worked with Tom Galley on Phenomena's "Blind Faith" album. - Ayreon is a musical project by Dutch songwriter, singer, multi-instrumentalist musician and record producer Arjen Anthony Lucassen. Ayreon's music is described as progressive rock, progressive metal and power metal sometimes combined with genres such as folk, electronica, experimental and classical music. The majority of Ayreon's albums are dubbed "rock operas" (or "metal operas") because the albums contain complex storylines featuring a host of characters, usually with each one being represented by a unique vocalist. - Shadow Gallery is an American progressive metal band formed in the Lehigh Valley, Pennsylvania, United States, during the early 1980s, originally under the name Sorcerer. After changing their name to Shadow Gallery (taken from the graphic novel "V for Vendetta" by Alan Moore) and recording a short 8-track demo, the band was signed to Magna Carta Records in 1991. Shadow Gallery's eponymous debut was released the following year in Japan and Europe. In mid-2005, Shadow Gallery released their fifth studio album, "Room V", on the European-American independent label InsideOut. - Robert John Arthur "Rob" Halford (born 25 August 1951) is an English singer and songwriter, who is best known as the lead vocalist for the Grammy Award-winning heavy metal band Judas Priest and famed for his powerful wide ranging operatic voice. AllMusic says of Halford: "There have been few vocalists in the history of heavy metal whose singing style has been as influential and instantly recognizable", possessing a voice which is "able to effortlessly alternate between a throaty growl and an ear-splitting falsetto". Halford was voted number 33 in the greatest voices in rock by Planet Rock listeners in 2009. In addition to his work with Judas Priest, he has been involved with several side projects, including Fight, 2wo and Halford. In 1998, he came out as gay in an interview with MTV news making him the first openly gay singer in mainstream heavy metal music. - Judas Priest are a British heavy metal band formed in Birmingham, England, in 1969. The band has sold close to 50 million albums to date. MTV ranked them the second greatest metal band of all time. Despite an innovative and pioneering body of work in the latter half of the 1970s, the band struggled with indifferently produced records, repeated changes of drummer and a lack of major commercial success or attention until 1980, when they adopted a more simplified sound on the album "British Steel", which helped shoot them to rock superstar status. In 1989, they were named as defendants in an unsuccessful lawsuit alleging that subliminal messages on the song "Better By You, Better Than Me" had caused the suicide attempts of two young men.
