The Ultimate Sin is the fourth studio album by Ozzy Osbourne. It was released on 22 February 1986, and it was remastered and re-issued on 22 August 1995. This album features guitarist Jake E. Lee (formerly of Mickey Ratt, Rough Cutt and Dio). This is the only Osbourne album to feature bassist Phil Soussan - who wrote the album's U.S. hit single "Shot in the Dark" - and the first to feature drummer, Randy Castillo. Lyrics were largely written by long-time Osbourne bass player Bob Daisley, who was also present during the initial writing sessions. Daisley left after having a disagreement with Osbourne, which led to the hiring of Soussan. He was also not credited as a co-writer on the initial 1986 pressing of the album. This was corrected on subsequent pressings. Drummer Jimmy DeGrasso worked with Lee and Daisley on demos for the album, but the band fell apart when Ozzy did the Black Sabbath Live Aid reunion in 1985, so Randy Castillo and Phil Soussan replaced DeGrasso and Daisley.

The original title for this album was Killer of Giants^{[citation needed]} (after the song of the same name) but Osbourne opted to change the title at the last minute, thus Killer of Giants became The Ultimate Sin.

The Absolute is the concept of an unconditional reality which transcends limited, conditional, everyday existence. It is sometimes used as an alternate term for "God" or "the Divine" especially, but by no means exclusively, by those who feel that the term "God" lends itself too easily to anthropomorphic presumptions. The concept of The Absolute may or may not (depending on one's specific doctrine) possess discrete will, intelligence, awareness or even a personal nature. It is sometimes conceived of as the source through which all being emanates. It contrasts with finite things, considered individually, and known collectively as the relative. This is reflected in its Latin origin absolūtus which means "loosened from" or "unattached."

Examples of religions and philosophies which embrace the concept of the Absolute in one form or another include Hermeticism, Hinduism, Jainism, Taoism, Islam, some forms of Jewish philosophy, and existential or metaphysical forms of Christianity. Terms which serve to identify The Absolute among such beliefs include Wu Chi, Brahman, Adibuddha, Allah, Para Brahman, Tetragrammaton, God, the Divine and numerous other appellations. In East Asia, the concept of the Tao, and in South Asia, the concept of Nirvana is synonymous in description to the attributes of the Absolute as used in the West.

John Michael "Ozzy" Osbourne (born 3 December 1948) is an English heavy metal vocalist and songwriter, whose musical career has spanned over 40 years. Osbourne rose to prominence as lead singer of the pioneering English band Black Sabbath, whose dark and hard sound helped spawn the heavy metal genre. Due to Sabbath's dark style, Osbourne became known as the "Prince of Darkness". Osbourne is also known as the "Godfather of Heavy Metal".

In the early 2000s, Osbourne's career expanded when he became a star in his own reality show The Osbournes, alongside wife/manager Sharon and two of their three children, Kelly and Jack. A documentary about his life and career, God Bless Ozzy Osbourne, premiered in April 2011 at the Tribeca Film Festival and was released on DVD in November 2011. Osbourne has achieved multi-platinum status as a solo artist and with Black Sabbath and has sold over 100 million albums worldwide.

John Michael "Ozzy" Osbourne was born in Aston, Birmingham, England, on 3 December 1948. His father Jack worked shifts as a toolmaker at GEC. His mother Lillian worked for the car components firm Lucas. John was the fourth of six children. Ozzy had two brothers (Paul and Tony) and three sisters (Jean, Iris and Gillian); they lived in a small two bedroom home at 14 Lodge Road in Aston. The nickname "Ozzy" was first used when he was in primary school. Although called "John" by his first wife Thelma, Osbourne states that it has been a long time since he's recognised himself when called by his formal name.

Jakey Lou Williams (born February 15, 1957 in Norfolk, Virginia, USA), commonly known as Jake E. Lee, is an American guitarist best known for playing with Ozzy Osbourne in the mid-1980s and later in his own band Badlands.

Jake E. Lee was encouraged by his mother to take classical piano lessons as a child. With a lack of interest in piano, 13 year old Lee found that he enjoyed playing his older sister's guitar. His older sister influenced his desire to play by introducing him to Jimi Hendrix, Black Sabbath and Led Zeppelin records. The first song he learned was "No Time" by The Guess Who. From there, he used what formal training he had from piano, along with a Mel Bay guitar method book and concentrated on becoming a self taught, rock guitarist. Obviously catching on and quickly developing a talent for the guitar, Lee played in several high school bands. And so, teenaged Jake E. Lee was already turning heads and wowing fellow San Diego musicians with his impressive style of playing, Jake Lee is now known to be named "Oh My Rambo" on the game SoulSplit created by Pim De Witte, his mum is #1 RS player IRL and he is a nong. Closely affiliated with Jamie '1991sparrow' Sparrow, Rs Brutality, paid both Jake Lee, and Jamie Sparrow to join the #1 Singles and Multi team.
